✦ Synopsis

1997 carboxylic acid esters carboxylic acid esters (benzene compounds) Q 0530 35 -098 Enantioselective Acyclic Stereoselection under Catalyst Control. Part 2. Asymmetric Synthesis of syn-and anti-1,3-Diols Incorporating an Acetate Equivalent by the Chiral Oxazaborolidinone-Catalyzed Aldol Reaction.

-Oxazaborolidinone-promoted aldol reaction provides a new method for acyclic stereoselection in the synthesis of 1,3-diol systems, useful intermediates for the preparation of natural products. The stereochemistry of compounds (V) and (VI) is not affected by the chiral center in (IV) but is strictly controlled by chiral catalyst used. -(KIYOOKA, S.; YAMAGUCHI,
