Abstract:

The phosphine catalyzed enantioselective [1+4]-annulation of 1-aryl-3-(thiazol-5-yl)prop-2-enone with Morita-Baylis-Hillman carbonate was developed, which enabled the formation of structurally diversified 2,3-dihydrofurans featuring thiazole skeleton in yields of 49%—96% with e.e. of 92%—99% and d.r. from 6∶1 to more than 20∶1. Notably, this work extended the application range of the established catalytic system and provided an excess to the chiral complex heterocyclic compounds containing dihydrofuran and thiazole structural units.

Key words: Asymmetric organocatalysis, Annulation, Thiazolyl enone, MBH carbonate, dihydrofuran
