Abstract
Efficient syntheses of synthetically important chiral 1,3,2-dioxaborol es have been developed. The reduction of 1,2-dicarbonyls with B-chloro diisopinocampheylborane, or a reaction of a-hydroxyketones with isopin ocampheyldichloroborane, provides rapid, convenient syntheses of chira l enediolboronates of the type, 2-isopinocampheyl-1,3,2-dioxaboroles. The latter procedure has been utilized to synthesize a series of 2-ter penyl-1,3,2-dioxaboroles from terpenyldichloroboranes. (C) 1997 Elsevi er Science Ltd.
