RING-OPENING OF OXIRANES BY SILYL-SUBSTITUTED ALLYL ANIONS. A REGIOCHEMICAL CHAMELEON
Schaumann, Ernst,Kirsching, Andreas
, p. 4281 - 4284 (1988)
Lithiated allylsilanes 1 undergo smooth addition to epoxides 4 with variable α,γ regioselectivity yielding the C-silylated enols 5,7 and 6,8, respectively. γ-Selectivity can be successfully enhanced by use of cuprates.
