Abstract
DNA tagging with base analogs has found numerous applications. To precisely record the DNA labelling information, it will be highly beneficial to develop chemical sequencing tags that can be encoded into DNA as regular bases and decoded as mutant bases upon a mild, efficient and bioorthognal chemical treatment. Here we reported such a DNA tag, N4-allyldeoxycytidine (a4dC), to label and identify DNA by in vitro assays. The iodination of a4dC led to fast and complete formation of 3, N4-cyclized deoxycytidine, which induced base misincorporation during DNA replication and thus could be located at single base resolution. We explored the applications of a4dC in pinpointing DNA labelling sites at single base resolution, mapping epigenetic mark N4-methyldeoxycytidine, and imaging nucleic acids in situ. In addition, mammalian cellular DNA could be metabolically labelled with a4dC. Together,our study sheds light on the design of next generation DNA tags with chemical sequencing power.

Chembiochem 2020; 21:3398-3409.

Abstract
Th formation of metal base pairs is a versatile method for the introduction of metal cations into nucleic acids that has been used in numerous applications including the construction of metal nanowires, development of energy, charge-transfer devices and expansion of the genetic alphabet. As an alternative, enzymatic construction of metal base pairs is an alluring strategy that grants access to longer sequences and offers the possibility of using such unnatural base pairs (UBPs) in SELEX experiments for the identification of functional nucleic acids. This method remains rather underexplored, and a better understanding of the key parameters in the design of efficient nucleotides is required. We have investigated the effect of methylation of the imidazole nucleoside (dImnMe TP) on the efficiency of the enzymatic construction of metal base pairs. The presence of methyl substituents on dImTP facilitates the polymerase-driven formation of dIm4Me -AgI -dIm and dIm2Me TP-CrIII -dIm base pairs. Steric factors rather than the basicity of the imidazole nucleobase appear to govern the enzymatic formation of such metal base pairs. We also demonstrate the compatibility of other metal cations rarely considered in the construction of artificial metal bases by enzymatic DNA synthesis under both primer extension reaction and PCR conditions. These findings open up new directions for the design of nucleotide analogues for the development of metal base pairs.

Abstract
A series of 2-alkylamino-2'-deoxyadenosine triphosphates (dATP) was prepared and found to be substrates for the Therminator DNA polymerase, which incorporated only one modified nucleotide into the primer. Using a template encoding for two consecutive adenines, conditions were found for incorporation of either one or two modified nucleotides. In all cases, addition of a mixture of natural dNTPs led to primer extension resulting in site-specific single modification of DNA in the minor groove. The allylamino-substituted DNA was used for the thiol-ene addition, whereas the propargylamino-DNA for the CuAAC click reaction was used to label the DNA with a fluorescent dye in the minor groove. The approach was used to construct FRET probes for detection of oligonucleotides.

Abstract
When we first heard of the Bürgenstock conference it was described as a guarded meeting in a remote location, undisturbed by modern diversions, with mysterious customs and a secret handshake. All of these rumors turned out to be completely true. We arrived at an undisclosed location and three young men, who knew our names upon sight, greeted us and gave us an agenda in which we discovered the identity of the speakers, moderators and other participants. We then had a few moments to bask in their glory before being treated to a delicious dose of chemistry. During the banquet, before the first lecture, this year's president, Prof. Ilan Marek, gave the opening address from a balcony reserved only for these meetings, rumors hold that it stands vacant all year in anticipation. He mentioned several of the traditions of the meeting, which we are not allowed to share of course, and described the joy of putting together this year's exciting program with the help of an exceptional organizing committee that included Prof. Cristina Nevado, Prof. Christian Bochet, Dr Fabrice Gallou and Dr Alain De Mesmaeker. He also introduced this year's guest of honor, Prof. Yitzhak Apeloig, and wished the best luck to the current Vice President and future President, Prof. Véronique Gouverneur, not only for preparing the 54th Bürgenstock Conference, but also with her duty this year, maintaining the good weather for the whole week. Although the official title of the conference is the EUCHEM conference on stereochemistry, the topics covered span a broad range of cutting edge chemical transformations and insights, which can appeal to anyone working in chemistry and its interfaces with other disciplines. We will briefly describe each of the talks following one of our favorite citable quotes from these inspiring speakers.

Abstract
The selection of artificial genetic polymers with tailor-made properties for their application in synthetic biology requires the exploration of new nucleosidic scaffolds that can be used in selection experiments. Herein, we describe the synthesis of a bicyclo-DNA triphosphate (i.e., 7',5'-bc-TTP) and show its potential to serve for the generation of new xenonucleic acids (XNAs) based on this scaffold. 7',5'-bc-TTP is a good substrate for Therminator DNA polymerase, and up to seven modified units can be incorporated into a growing DNA chain. In addition, this scaffold sustains XNA-dependent DNA synthesis and potentially also XNA-dependent XNA synthesis. However, DNA-dependent XNA synthesis on longer templates is hampered by competitive misincorporation of deoxyadenosine triphosphate (dATP) caused by the slow rate of incorporation of 7',5'-bc-TTP.

Abstract
Efficient incorporation of modified nucleotides by DNA polymerases is essential for many cutting-edge biomolecular technologies. The present study compares the acceptance of either alkene- or alkyne-modified nucleotides by KlenTaq DNA polymerase and provides structural insights into how 7-deaza-adenosine and deoxyuridine with attached alkene-modifications are incorporated into the growing DNA strand. Thereby, we identified modified nucleotides that prove to be superior substrates for KlenTaq DNA polymerase compared with their natural analogues. The knowledge can be used to guide future design of functionalized nucleotide building blocks.

Abstract
2'-Deoxyadenosine triphosphate (dATP) derivatives bearing diverse substituents (Cl, NH2 , CH3 , vinyl, ethynyl, and phenyl) at position 2 were prepared and tested as substrates for DNA polymerases. The 2-phenyl-dATP was not a substrate for DNA polymerases, but the dATPs bearing smaller substituents were good substrates in primer-extension experiments, producing DNA substituted in the minor groove. The vinyl-modified DNA was applied in thiol-ene addition and the ethynyl-modified DNA was applied in a CuAAC click reaction to form DNA labelled with fluorescent dyes in the minor groove.
