Abstract: [GRAPHICS] Good levels of substrate-controlled, 1,5-syn-stereoinduction are obtained in boron-mediated aldol reactions of beta-trichloromethyl-beta-alkoxy and beta-trifluoromethyl-beta-alkoxy methylketones with achiral aldehydes, independent of the nature of the beta-alkoxy protecting group (TBS or PMB). In the case of boron aldol reactions of beta-aryl-beta-alkoxy methylketones, the 1,5-anti-adducts were obtained with high levels of diastereoselectivity only with a beta-OPMB group.
