摘要

A quinine-derived thiourea-catalyzed enantioselective double annulation strategy using alkylidene Meldrum′s acid as an acceptor-donor-acceptor with salicylaldehyde-derived azomethine ylide is reported. The methodology is realized via a (3+2) cycloaddition/transesterification/decarboxylation sequence, giving chromeno[4,3-b]pyrrolidines within 15–420 minutes at room temperature in 51–97% yields with 92–99% ee under 1–10 mol% catalyst loading. A plausible activation model is proposed for the excellent stereoinduction by H-bond interaction between the catalyst and the Meldrum′s acid motif according to control experiments.
