Abstract
We report late-stage ring-opening metathesis (ROM), ring-rearrangement metathesis (RRM), and ring-closing metathesis (RCM) approaches to generate expanded pentacycloundecane (PCUD) cage derivatives. These higher-order intricate polycyclic cage systems are aesthetically pleasing and structurally intriguing. Their assembly maintains molecular symmetry during the entire synthetic sequence. To this end, metathesis-based catalysts are used to execute the ROM, RRM, and RCM strategies. The synthetic approach to these cage polycycles involves the Diels-Alder reaction, [2 + 2] photocycloaddition, RRM, ROM, and RCM as key steps.

Abstract
Downstream processing to obtain enantiopure compounds from a racemic mixture relies mainly on crystallization. Natural transporters can specifically translocate enantiomers through membranes. Here a β-barrel transmembrane protein FhuA is re-engineered into a chiral channel protein (FhuAF4) to resolve racemic mixtures of d-/l-arginine. The engineered FhuAF4 variant exhibits an enantioselectivity (E-value) of 1.92 and an enantiomeric excess percentage (ee%) of 23.91 at 52.39% conversion. OmniChange mutant libraries at the computationally identified "filter-regions" likely help to identify FhuA variants for enantiomeric separation of other compounds.

Enantioselective Extraction System Containing Binary Chiral Selectors and Chromatographic Enantioseparation Method for Determination of the Absolute Configuration of Enantiomers of Cyclopentolate.

Abstract
The distribution coefficients and enantioseparation of cyclopentolate were studied in an extraction system containing d-tartaric acid ditertbutyl ester in organic phase and 2-hydroxypropyl-β-cyclodextrin (HP-β-CD) in aqueous phase. Various parameters involved in the enantioseparation such as the type and the concentration of chiral selectors, pH value and a wide range of organic solvents were investigated. The maximum enantioselectivity (α = 2.13) and optimum distribution coefficients (KR = 0.85, KS = 0.40) were obtained under the following conditions: 0.10 mol/L HP-β-CD in aqueous phase and 0.20 mol/L d-tartaric acid ditertbutyl ester in decanol as organic phase. Cyclopentolate is present as a racemic mixture to the aqueous phase. The potentially different biological activities of cyclopentolate enantiomers have not been examined yet. Two chiral liquid chromatography methods have been developed for the direct separation of the enantiomers of cyclopentolate. First method was used for the quantification analysis of cyclopentolate enantiomers in aqueous phase. Second method used two chiroptical detectors: electronic circular dichroism (ECD) and optical rotation (OR) for the identification of individual cyclopentolate enantiomers from the organic phase enriched with (R)-enantiomer. The absolute stereochemistry was determined by means of the comparison of the experimental and computed ECD spectra and signs of OR. The ECD spectra of chiral analytes were measured on-line using HPLC-ECD technique.

Abstract
Recent advances in enantioselective metal-catalyzed oxidations are presented. Two transformations are discussed in detail: (a) asymmetric Baeyer-Villiger reactions of racemic and prochiral cyclic ketones giving optically active lactones, and (b) sulfide oxidations affording enantiomerically enriched sulfoxides. For both reactions, new metal/ligand combinations have been introduced which allow catalysis of these reactions with high enantioselectivities. For some substrates, the ee-values are above 90%. As previously demonstrated, sulfoxides can be iminated to give the corresponding sulfoximines. Under appropriate reaction conditions, this transformation is stereospecific and enantiopure sulfoximines are obtained. These highly oxidized sulfur reagents have now been modified to give beta-amino acid analogues which may be incorporated into peptides. Two variants have been realized: either the sulfoximine-containing pseudo-amino acids are connected with standard alpha-amino acids to give mixed pseudopeptides, or the sulfoxime units are mutually attached to give homooligomers, which can be regarded as beta-peptide analogues.
