A direct method for the conversion of terminal epoxides into γ-butanolides
Movassaghi, Mohammad,Jacobsen, Eric N.
, p. 2456 - 2457 (2007/10/03)
A new and efficient process for the conversion of terminal epoxides to γ-butanolides is described involving Lewis acid promoted epoxide ring-opening by 1-morpholino-2-trimethylsilyl acetylene. Addition of a terminal epoxide to a solution of the ynamine an
