摘要：

The substrate-based stereocontrol observed in the sulfur ylide mediated cyclopropanation of cis-beta-cyclopropyl-alpha,beta-unsaturated esters is complementary to that observed with zinc-carbenoids. The selectivity for preparation of the cis-syn-trans-bis-cyclopropane, although modest, is superior to previous substrate and reagent-mediated processes. Copyright (C) 1996 Elsevier Science Ltd
