Journal ArticleDOI
Purification and characterization of two oxidoreductases involved in the enantioselective reduction of 3-oxo, 4-oxo and 5-oxo esters in baker's yeast
TL;DR: Two NADPH-dependent oxidoreductases catalyzing the enantioselective reduction of 3-oxo esters to (S)- and (R)-3-hydroxy acid esters have been purified 121- and 332-fold from cell extracts of Saccharomyces cerevisiae.
Journal ArticleDOI
Asymmetric Diels‐Alder Reactions of Neopentyl‐Ether‐Shielded Acrylates and Allenic Esters: Syntheses of (−)‐Norbornenone and (−)‐β‐Santalene
TL;DR: In this article, a cycloaddition of cyclopentadiene to allenic ester with 95 % endo-and 99.2% πpH-face selectivities was proposed.
Journal ArticleDOI
A novel approach to the synthesis of optically pure non protein α-amino acids in both L and D configurations from L-serine
TL;DR: In this paper, the (2R)-2-Boc-amino-3-phenylsulfonyl-l-propanol 3 and its enantiomer 9 from L-serine are described.

Enantioselective conjugate addition to cyclic enones with scalemic lithium organo(amido)cuprates, Part IV. Relationship between ligand structure and enantioselectivity
Bryant E. Rossiter,Masakatsu Eguchi,Guobin Miao,Nicole M. Swingle,A. E. Hernandez,Denise Vickers,Ezdan Fluckiger,R. Greg Patterson,K. Vásavi Reddy +8 more
TL;DR: In this paper, the most successful chiral ligand is (S)-N-methyl-1-phenyl-2-(1-piperidinyl)ethanamine, 13, which reacts with cyclic enones to form products with up to 97% ee.
Journal ArticleDOI
Mangicols: Structures and Biosynthesis of A New Class of Sesterterpene Polyols from a Marine Fungus of the Genus Fusarium
TL;DR: A marine fungal isolate, tentatively identified as Fusarium heterosporum, has been found to produce a series of structurally novel sesterterpene polyols, the mangicols A-G, which show only weak to modest cytotoxicities toward a variety of cancer cell lines in in vitro testing.
