V. Michelet et al., ASYMMETRIC-SYNTHESIS OF SUBSTITUTED FUNCTIONALIZED CIS AND TRANS VINYLCYCLOPROPANES VIA PALLADIUM-CATALYZED REACTIONS, Synlett, (3), 1996, pp. 215
A facile method for synthesizing irons and cis disubstituted vinylic c
yclopropanes is described. The key steps are alkylation of chiral ally
lic alcohols and cyclisation via SN Of functionalized allylic substrat
es using palladium (0) catalyst with high regio- and stereoselectivity
