Simple synthetic method of allyl- and vinyl-epoxides by allylation of carbonyl groups with allylic tins catalyzed by PbI2-HMPA

Article abstract of DOI:10.1246/cl.1998.533

Allyl epoxides were prepared by the chemoseletive allylation at the carbonyl groups of a-bromo ketones with allylic tin, where PbI₂-HMPA effected as a chemoselective catalyst. Moreover, vinyl epoxides were obtained in one pot procedure by the P
