资源简介：
A novel and facile synthesis of azaspiro-γ-lactones with a methylene–lactam framework from N-carbonyl imides is described. Mechanistic investigations provide evidence for a two-step reaction process involving ZnCl2-promoted addition of β-amido allylindium species followed by an unexpectedly molecular-sieves-mediated ring opening–reclosure concomitantly with the loss of an N-carbonyl unit.
