A practical new chiral controller for asymmetric Diels-Alder and alkylation reactions

(formula presented) The enantiomerically pure hydroxy sulfones (+)- and (-)-2 have been prepared from 1,2-epoxycyclohexane by a simple and practical procedure. The acrylate esters of these alcohols undergo BCl3-catalyzed Diels-Alder reactions with a variety of dienes at -78 to -55°C in CH2Cl2 or C7H8 with high dienophile face selectivity (Table 1). The chiral esters so formed are readily cleaved with recovery of the controllers (+)- or (-)-2. Esters of (+)- and (-)-2 can be converted to Z-polassium enolates and alkylated with high face selectivity.

Kinetic Resolution of α-Arylcarboxylic Acid Derivatives by a Catalytic Use of a Chiral Titanium Alkoxide

Kinetic resolution of racemic α-arylcarboxylic acids is successfully achieved by a catalytic use of titanium tetraisopropoxide and a chiral 1,4-diol in the reaction of the corresponding 2-pyridinethiol esters and isopropyl alcohol.
