title: The influence of a beta-electron withdrawing substituent in aldol reactions of methylketone boron enolates.
abstract: We wish to describe here that good levels of substrate-based, 1,5-syn-stereocontrol could be achieved in the boron-mediated aldol reactions of beta-trichloromethyl methylketones with achiral aldehydes, independent of the nature of the beta-alkoxy protecting group.
