摘要

Starting either from benzoylformic acid or ethyl oxamate and enantiopure β-amino alcohols, several chiral α-hydroxy oxazolines have been prepared by short synthetic routes. Subsequently, they have been employed in the catalytic asymmetric phenyl transfer to various aldehydes, using a mixture of triphenylborane and diethylzinc as the phenyl source. The corresponding secondary alcohols were obtained with good enantioselectivities (up ...
