THE REACTION OF α,β-EPOXYSILANES WITH METALLATED ALKYLARYL SULPHONES. A NOVEL APPROACH TO ALLYLIC ALCOHOLS
Masnyk, Marek,Wicha, Jerzy
, p. 2497 - 2500 (2007/10/02)
Lithiated alkylaryl sulphones (2a-c) react with α,β-epoxysilane (1) to yield O-trimethylsilyl allylic alcohols (3a-c), predominantly as Z isomers.The BF3-assisted reaction followed by treatment of the adduct with nBu4NF affords allylic alcohols.
