The addition of dialkylzincs to aldehydes is accelerated considerably by the presence of a catalytic amount of o -hydroxybenzylamine ( R , R )- 2e to give...
Investigates the rate and enantioselectivity of chiral beta-dialkylamino alcohol-promoted alkylation of aldehydes by dialkylzincs where a tricoordinate alk...

Enantioselective Addition of Dialkylzincs to Aldehydes Promoted by Chiral Amino Alcohols. Mechanism and Nonlinear Effect. J. Am. Chem. Soc. 1989, 111, ...
Zearalenone (ZEA) mainly injures the reproductive system of mammals. In the present study, we aimed to explore the mechanism by which zinc inhibits ZEA-ind...
We demonstrate that α-(aminomethyl)acrylates are suitable acceptors for 1,4-additions of dialkylzincs in aerobic conditions. The air-promoted radical-pola...
Important advances are being made in the development of stereoselective organic reactions. Some of the emerging research directions that hold forth great promise in this area deal with the development of chiral catalysts for these proces...
Both enantiomers of sec-alcohols were obtained in high enantiomeric excess (up to 92%) from the enantioselective addition of diethylzinc to aldehydes using...
The configuration of α-aminocamphor was determined from NMR studies, the mechanism for the syntheses of α- and β-aminoborneols elucidated, and 2- exo-hydroxy-3- exo-aminobornane, a new diastereoisomer of 2-hydroxy-3-aminobornane synth...
