THE REACTION OF TRIALKYLSTANNYLMETHYLLITHIUM WITH α,β-EPOXY KETONES. A PREPARATIVE METHOD OF β,γ-UNSATURATED KETONES BY HOMOLOGATION OF α,β-UNSATURATED KETONES

Sato, Tadashi,Kikuchi, Toshihiro,Sootome, Norio,Murayama, Eigoro

, p. 2205 - 2208 (1985)

α,β-Epoxy ketones 2, upon treatment with two equivalents of trialkylstannylmethyllithium 1, afforded cyclopropanols 3 as a single product in acyclic system, and a mixture of cyclopropanols 3 and methylene 1,2-diols 4 in cyclic system.Under acidic conditions, the cyclopropanols gave β,γ-unsaturated ketones 5 in good yields.
