ligand controlled stereodivergent enantioselective conjugate addition of 2 oxazoline and 2 thiazoline 4 carboxylate to nitroalkene catalyzed by chiral copper complexes
Journal of Organic Chemistry, 2016Co-Authors: Yukiko Matsuda, Akihiro Koizumi, Ryosuke Haraguchi, Shinichi FukuzawaAbstract:The copper-catalyzed asymmetric conjugate addition of 2-oxazoline- and 2-thiazoline-4-carboxylate to a nitroalkene proceeded to give either the syn or anti adduct selectively in high enantiomeric excess when an appropriate chiral ligand was used. Subsequent reduction of the nitro group followed by hydrolysis of the oxazoline ring yielded an optically active γ-lactam of protected α-quaternary Serine Derivative.

chiral molecular recognition in monolayers of diastereomeric n acylamino acid methyl esters at the air water interface
Journal of the American Chemical Society, 1992Co-Authors: Jonathan Heath, Edward M. ArnettAbstract:This article continues our study of the effects of headgroup geometry and temperature on chiral recognition in the force-area isotherms, thermodynamics of spreading, and surface shear viscosities of monolayers and mixed monolayers of long-chain amino acid ester surfactants. N-Stearoyl-and lauroyl-Derivative of the methyl esters of cysteine, cystine, and threonine are compared to the previously-reported Serine Derivative. The structural points at issue are as follows: (a) the effects of replacing the hydroxyl group of Serine with the thiol group of cysteine
