Abstract
This critical review discusses recent developments in the field of cyclopropene chemistry. Although several excellent reviews that mainly focused on the thermolysis and pyrolysis as well as metal-mediated reactions of cyclopropenes have been published, significant new developments have also been achieved in recent years. This brand new review provides an overview of the progress from 2007 to 2011 on the syntheses and transformations of cyclopropenes as well as their related mechanistic studies (238 references).

Abstract
A two-step process based on copper-free click chemistry is described, by which the surface of silicon nanowires can be functionalized with specific organic substituents. A hydrogen-terminated nanowire surface is first primed with a monolayer of an α,ω-diyne and thereby turned into an alkyne-terminated, clickable platform, which is subsequently coupled with an overlayer of an organic azide carrying the desired terminal functionality. The reactive, electron-deficient character of the employed diyne enabled a quantitative coupling reaction at 50 °C without metal catalysis, which opens up a simple and versatile route for surface functionalization under mild conditions without any potentially harmful additives.

Abstract
![]()
Many developmental processes depend on proper fucosylation, but this post-translational modification is difficult to monitor in vivo. Here we applied a chemical reporter strategy to visualize fucosylated glycans in developing zebrafish. Using azide-derivatized analogues of fucose, we metabolically labeled cell-surface glycans and then detected the incorporated azides via copper-free click chemistry with a difluorinated cyclooctyne probe. We found that the fucose salvage pathway enzymes are expressed during zebrafish embryogenesis but that they process the azide-modified substrates inefficiently. We were able to bypass the salvage pathway by using an azide-functionalized analogue of GDP-fucose. This nucleotide sugar was readily accepted by fucosyltransferases and provided robust cell-surface labeling of fucosylated glycans, as determined by flow cytometry and confocal microscopy analysis. We used this technique to image fucosylated glycans in the enveloping layer of zebrafish embryos during the first 5 days of development. This work provides a method to study the biosynthesis of fucosylated glycans in vivo.

Abstract
Cross-linked DNA was constructed by a "stepwise click" reaction using a bis-azide. The reaction is performed in the absence of a template, and a monofunctionalized oligonucleotide bearing an azido-function is formed as intermediate. For this, an excess of the bis-azide has to be used compared to the alkynylated oligonucleotide. The cross-linking can be carried out with any alkynylated DNA having a terminal triple bond at any position of the oligonucleotide, independent of chain length or sequence with identical or nonidentical chains. Short and long linkers with terminal triple bonds were introduced in the 7-position of 8-aza-7-deaza-2'-deoxyguanosine (1 or 2), and the outcome of the "stepwise" click and the "bis-click" reaction was compared. The cross-linked DNAs form cross-linked duplexes when hybridized with single-stranded complementary oligonucleotides. The stability of these cross-linked duplexes is as high as respective individual duplexes when they were ligated at terminal positions with linkers of sufficient length. The stability decreases when the linkers are incorporated at central positions. The highest duplex stability was reached when two complementary cross-linked oligonucleotides were hybridized.

Abstract
Computation was used to design a trans-cyclooctene derivative that displays enhanced reactivity in the tetrazine-trans-cycloctene ligation. The optimized derivative is an (E)-bicyclo[6.1.0]non-4-ene with a cis-ring fusion, in which the eight-membered ring is forced to adopt a highly strained 'half-chair' conformation. Toward 3,6-dipyridyl-s-tetrazine in MeOH at 25 °C, the strained derivative is 19 and 27 times more reactive than the parent trans-cyclooctene and 4E-cyclooct-4-enol, respectively. Toward 3,6-diphenyl-s-tetrazine in MeOH at 25 °C, the strained derivative is 160 times more reactive than the parent trans-cyclooctene.

Abstract
1,3-Dipolar [3 + 2] cycloaddition between azides and alkynes--an archetypal "click" chemistry--has been used increasingly for the functionalization of nucleic acids. Copper(I)-catalyzed 1,3-dipolar cycloaddition reactions between alkyne-tagged DNA molecules and azides work well, but they require optimization of multiple reagents, and Cu ions are known to mediate DNA cleavage. For many applications, it would be preferable to eliminate the Cu(I) catalyst from these reactions. Here, we describe the solid-phase synthesis and characterization of 5'-dibenzocyclooctyne (DIBO)-modified oligonucleotides, using a new DIBO phosphoramidite, which react with azides via copper-free, strain-promoted alkyne-azide cycloaddition (SPAAC). We found that the DIBO group not only survived the standard acidic and oxidative reactions of solid-phase oligonucleotide synthesis (SPOS), but that it also survived the thermal cycling and standard conditions of the polymerase chain reaction (PCR). As a result, PCR with DIBO-modified primers yielded "clickable" amplicons that could be tagged with azide-modified fluorophores or immobilized on azide-modified surfaces. Given its simplicity, SPAAC on DNA could streamline the bioconjugate chemistry of nucleic acids in a number of modern biotechnologies.

Abstract
Two in one--We show here that the highly strained trans,trans-diolefin (E,E)-1,5-cyclooctadiene can perform efficiently two different click reactions at fast reaction rates. It is capable of first undergoing [3+2] cycloadditions with 1,3-dipoles at a reaction rate comparable to that of strained cyclooctynes. The resulting cycloadduct can then perform a much faster inverse-electron-demand Diels-Alder reaction with tetrazines, effectively linking an azide to a tetrazine. Thus, (E,E)-1,5-cyclooctadiene could have many applications in chemical biology and polymer chemistry.

Abstract
Templated DNA strand ligation by the ring-strain promoted alkyne-azide [3+2] cycloaddition reaction is very fast; with dibenzocyclooctyne, the reaction is essentially complete in 1 min. It is inhibited by the presence of a single mismatched base pair suggesting applications in genetic analysis.

Abstract
Recapitulating the elegant structures formed during development is an extreme synthetic and biological challenge. Great progress has been made in developing materials to support transplanted cells, yet the complexity of tissues is far beyond that found in even the most advanced scaffolds. Self-assembly is a motif used in development and a route for the production of complex materials. Self-assembly of peptides, proteins and other molecules at the nanoscale is promising, but in addition, intriguing ideas are emerging for self-assembly of micron-scale structures. In this brief review, very recent advances in the assembly of micron-scale cell aggregates and microgels will be described and discussed.

5-Hydroxymethylcytosine (5-hmC) is a newly discovered DNA base in mammalian cells that is believed to be another important epigenetic modification. Here we report the use of a methylation-insensitive restriction enzyme Taq(α)I coupled with selective chemical labeling of 5-hmC in a combined glycosylation restriction analysis (CGRA) to detect 5-hmC in TCGA sequences. This method, differentiates fully versus hemi-hydroxymethylated cytosine in the CpG dinucleotide, adds a new tool to facilitate biological studies of 5-hmC.

Abstract
Click-free imaging of the nuclear localization of an alkyne-tagged cell proliferation probe, EdU, in living cells was achieved for the first time by means of Raman microscopy. The alkyne tag shows an intense Raman band in a cellular Raman-silent region that is free of interference from endogenous molecules. This approach may eliminate the need for click reactions in the detection of alkyne-labeled molecules.

Abstract
Tuberculosis (TB), which is caused by Mycobacterium tuberculosis (Mtb), is a major worldwide threat to public health. Mycobacterium protein tyrosine phosphatase B (mPTPB) is a virulent phosphatase secreted by Mtb, which is essential for the survival and persistence of the bacterium in the host. Consequently, small-molecule inhibitors of mPTPB are expected to serve as anti-TB agents with a novel mode of action. Herein, we report the discovery of highly potent and selective mPTPB inhibitors using a novel, double Click chemistry strategy. The most potent mPTPB inhibitor from this approach possesses a K(i) value of 160 nM and a >25-fold selectivity for mPTPB over 19 other protein tyrosine phosphatases (PTBs). Molecular docking study of the enzyme-inhibitor complex provides a rationale for the high potency and selectivity of the lead compound and reveals an unusual binding mode, which may guide further optimization effort.

Abstract
The advances in bioorthogonal ligation methods have provided new opportunities for proteomic analysis of newly synthesized proteins, posttranslational modifications, and specific enzyme families using azide/alkyne-functionalized chemical reporters and activity-based probes. Efficient enrichment and elution of azide/alkyne-labeled proteins with selectively cleavable affinity tags are essential for protein identification and quantification applications. Here, we report the synthesis and comparative analysis of Na₂S₂O₄-cleavable azobenzene-based affinity tags for bioorthogonal chemical proteomics. We demonstrated that ortho-hydroxyl substituent is required for efficient azobenzene-bond cleavage and show that these cleavable affinity tags can be used to identify newly synthesized proteins in bacteria targeted by amino acid chemical reporters as well as their sites of modification on endogenously expressed proteins. The azobenzene-based affinity tags are compatible with in-gel, in-solution, and on-bead enrichment strategies and should afford useful tools for diverse bioorthogonal proteomic applications.

Abstract
Reductive cyclization of aryl and vinyl iodides tethered to vinylogous acyl triflates (VATs) induces a ring-expanding fragmentation to provide cyclic alkynyl ketones, including strained nine-membered cycloalkynes, in fair to excellent yield. The tandem cyclization/C-C bond-cleavage is initiated under carefully optimized conditions by halogen-metal exchange in the presence of carbonyl and vinyl triflate functionality. A modified protocol for alkylation of 1,3-cyclohexanedione is described for preparing the relevant VAT substrates.

Abstract
Organomicelles modified by surface dibenzylcyclooctyne moieties can conveniently be functionalized by strain-promoted alkyne-azide cycloadditions. The ligation approach is highly efficient, does not require toxic reagents and is compatible with a wide variety of functional modules. Interactions of proteins with surface ligands of the micelles have been studied by AFM, which revealed that it leads to disassembly of the particles thereby providing a mechanism for triggered drug release.

Abstract
Oxidation of protein (bovine albumin serum) by air still occurred under the copper-catalyzed azide-alkyne cycloaddition (CuAAC) reaction conditions even in the presence of a Cu(I)-stabilizing tris(triazole) ligand. Anaerobic conditions not only avoided the oxidation of the protein, but also greatly accelerated the CuAAC reaction using a water-soluble bis(triazole) Cu(I) ligand.

Abstract
With the increasing requirement for analysis and separation of samples related to genomics, proteomics, metabolomics, pharmacology and agrochemistry, diverse stationary phases for liquid chromatography have been prepared by Cu(i)-catalyzed 1, 3-dipolar azide-alkyne cycloaddition reaction (CuAAC). It has been proved that CuAAC is a powerful tool for preparing covalently bonded stationary phases. In this tutorial review, we highlighted the preparation of separation materials by immobilization of functional groups on silica beads, polymer beads and agarose via CuAAC and their applications in liquid chromatography and related purposes, such as separation of polar compounds, enrichment of valuable bio-samples, orthogonal two-dimensional HPLC and chiral separation. Meanwhile, agarose-based separation materials for affinity chromatography are reviewed.

Abstract
Major advances have been made in exploring the transglycosylation activity of endo-β-N-acetylglucosaminidases (ENGases) for synthetic purpose. The exploration of synthetic sugar oxazolines as donor substrates for the ENGase-catalyzed transglycosylation has expanded the substrate availability and significantly enhanced the overall transglycosylation efficiency. On the other hand, site-directed mutagenesis in combination with activity screening has led to the discovery of the first generation ENGase-based glycosynthases that can use highly active sugar oxazolines as substrates for transglycosylation but lack hydrolytic activity on the ground-state products. ENGases have shown amazing flexibility in transglycosylation and possess much broader substrate specificity than previously thought. Now the ENGase-based chemoenzymatic method has been extended to the synthesis of a range of complex carbohydrates, including homogeneous glycopeptides, glycoproteins carrying well-defined glycans, novel oligosaccharide clusters, unusually glycosylated natural products, and even polysaccharides. This article highlights recent advances related to ENGase-catalyzed transglycosylation with a focus on their synthetic potential.

Abstract
Glycosylphosphatidylinositol (GPI) anchorage is a common posttranslational modification of eukaryotic proteins. Chemical synthesis of structurally defined GPIs and GPI derivatives is a necessary step toward understanding the properties and functions of these molecules in biological systems. In this work, the synthesis of several functionalized GPI anchors was accomplished using the para-methoxybenzyl (PMB) group for permanent hydroxyl protection, which allowed the incorporation of functionalities that are incompatible with permanent protecting groups traditionally used in carbohydrate synthesis. A flexible convergent-divergent assembly strategy enabled efficient access to a diverse set of target structures, including "clickable" Alkynyl-GPIs 1 and 2 and Azido-GPI 3. For global deprotection, a one-pot reaction was employed to afford the target GPIs in excellent yields (85-97%). Fully deprotected clickable GPIs 2 and 3 were readily conjugated to imaging and affinity probes via Cu(I)-catalyzed and Cu-free strain-promoted [3+2] cycloaddition, respectively, resulting in GPI-Fluor 4 and GPI-Biotin 5.

Abstract
Two reagents have been synthesized for selective labeling of cell surface azidoglycans, an unusually stable version of a dibenzocyclooctyne (TMDIBO) and a third-generation difluorinated cyclooctyne (DIFO3). Both syntheses are efficient with minimal purification, and the dibenzocyclooctyne is stable under basic and acidic conditions. Flow cytometric measurements with azidosugar labeled cancer cells, in which these reagents were linked to the fluorophore Alexa Fluor 647, gave a signal-to-background ratio of up to 35 with TMDIBO as compared to ≈10 for DIFO3 and ≈5 for a phosphine reagent. TMDIBO-based probes should have applications in molecular imaging of cell surface glycans in vivo.
