  摘要：

  Boron-mediated asymmetric aldol reactions of substituted benzaldehyde 5 with 2-oxyethanoyloxazolidinones 4a-e, containing electron withdrawing, chelating, and bulky alkoxy and aryloxy groups, gave variable yields of synaldol adducts 6a-e in high diastereoisomeric excess. Dehydroxylation of these adducts afforded 7a-e in a sequence which complements the traditional Evans asymmetric alkylation strategy. Cleavage of the auxiliary from 7a-e afforded antihyperglycaemic (S)-(-)-2-oxy-3-arylpropanoic acids 3a-e in excellent enantiomeric excess. (C) 1999 Elsevier Science Ltd. All rights reserved.
