摘要:
The reaction of sulfonium ylides with enones 5 derived from (S)-Garner's aldehyde in toluene provides 1,2,3-trisubstituted cyclopropanes. The configuration of the major isomer is 2R,1'R,2'R,3'R. Using this reaction a 3-benzyl analogue of the CCG family compounds was synthesized. (C) 2000 Elsevier Science Ltd. All rights reserved.
