摘要

Abstract N-Protected α-amino-α-vinyl-γ-butyrolactones 1 are obtained by the aza-Michael- type addition of NsONHCO 2 Et to novel silylated α-ylidene-γ-butyrolactones 2, through ring opening of the intermediate aziridine and loss of the trimethylsilyl group. The stereoselective synthesis of compounds 2, by cross-coupling reactions between α-[(triflyloxy) ylidene]-γ- butyrolactones 3 and tris [(trimethylsilyl) methyl] aluminum, is also described.(© Wiley- ...
