Vinylogous and stereoselective domino synthesis of pyrano[2,3- c]pyrroles from alkylidene meldrum's acids

Org Biomol Chem. 2024 Apr 17;22(15):2948-2952. doi: 10.1039/d4ob00233d.

Abstract

A domino Vinylogous aza-Michael-Aldol-Cyclocondensation (aza-VMAC) reaction was achieved with a series of alkylidene Meldrum's acid derivatives under simple operational conditions paving the way to novel pyrano[2,3-c]pyrroles in an excellent diasteroselectivity (>96 : 4), encompassing the relative control of three contiguous stereocenters.
