The Julia-Colonna asymmetric epoxidation reaction of substituted benzalacetophenone afforded the corresponding epoxide with high yield and high enantioselectivity, catalyzed by the specified length of poly-l-leucine (chain length n > 15). Poly-l-leucine catalysts have been prepared by the polymerization reaction of l-leucine-NCA with initiators (BnONa, n-BuNH2, H2O) and characterized by the MALD1-TOF Mass and IR analysis.

The first total synthesis of (+)-8-epi-xanthatin (1) has been achieved in 14 steps starting from the commercially available ester 24, which was converted into aldehyde 23 in six steps. An enantioselective aldol reaction of 23 gave 30, which was transformed into triflate 22 in four steps, setting the stage for a palladium-catalyzed carbonylation reaction to form acrylate 34. Compound 34 was then subjected to a deprotection/lactonization sequence to furnish enyne 21, which underwent a domino enyne ring-closing metathesis/cross metathesis process to form a seven-membered carbocycle and (E)-conjugated dienone, thereby completing the synthesis of 1. This domino ruthenium-catalyzed metathesis reaction thus serves as an efficient method to construct the core of xanthanolide and other sesquiterpene lactones.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 144542-43-8

In response to a recent literature report by Decicco and Leathers, the work of Hale, Delisser, and Manaviazar (1992) on the asymmetric synthesis of (3R)- and (3S)-piperazic acids has been reinvestigated, and the originally claimed product yields fully substantiated. The claims made in reference 13 about the proportions of cyclised product 6 and starting bromide 20 isolated from the low temperature electrophilic hydrazination-nucleophilic cyclisation of 20 with di-t-butylazodicarboxylate (DBAD) and DMPU as an additive are inaccurate. The retro-hydrazination reaction that they claim is problematic when DMPU is added to the hydrazinated reaction mixture has been demonstrated not to have a seriously detrimental effect on cyclisation product yield and to be unimportant. The other main ion of reference 13, that the electrophilic hydrazination and nucleophilic cyclisation of 20 gives 6 in 91% isolated yield when n-Bu4NI is employed as an additive (instead of DMPU) has also been shown to be in error. We have carefully repeated a scaled-down version of the n-Bu4NI catalysed procedure and have found that 6 is generally isolated in yields of 50-56% after flash chromatography. We have concluded that n-Bu4NI does not significantly increase the yields of cyclisation products 6 or 17 when it is employed as a cyclisation additive. Herein, we report details of our two preferred ‘crude’ experimental procedures for preparing the enantiomers of piperazic acid in high optical purity, neither of which requires chromatographic purification of the reaction intermediates en route. Both these preferred ‘crude’ methods for preparing 11 and 19 have been consistently reproduced many times in these laboratories over the past few years. In our view, they remain the most expedient and highest yielding methods currently available for obtaining 11 and 19 in high optical purity.

Methanethiosulfonate reagents may be used to introduce virtually unlimited structural modifications in enzymes via reaction with the thiol group of cysteine. The covalent coupling of enantiomerically pure (R) and (S) chiral auxiliary methanethiosulfonate ligands to cysteine mutants of subtilisin Bacillus lentus induces spectacular changes in catalytic activity between diastereomeric enzymes. Amidase and esterase kinetic assays using a low substrate approximation were used to establish k(cat)/K(M) values for the chemically modified mutants, and up to 3-fold differences in activity were found between diastereomeric enzymes. Changing the length of the carbon chain linking the phenyl or benzyl oxazolidinone ligand to the mutant N62C by a methylene unit reverses which diastereomeric enzyme is more active. Similarly, changing from a phenyl to benzyl oxazolidinone ligand at S166C reverses which diastereomeric enzyme is more active. Chiral modifications at S166C and L217C give CMMs having both high esterase k(cat)/K(M)’s and high esterase to amidase ratios with large differences between diastereomeric enzymes.
