✦ Synopsis

Chromium alkoxycarbene complexes tethered to a triple bond react with a series of chiral dihydropyridines, among which is N-methyl-1,2-dihydronicotine, to give enantioselectively, upon cascade insertion reactions, polycyclic butenolides.

A series of new substituted butenolides has been obtained either by reacting alkynylalkoxycarbene complexes 3 with simple nucleophiles such as metal hydrides, metal alkoxides and metal alkyls, or by reacting simple alkoxycarbene complexes 6 with more elaborate nucleophiles such as metal alkynolates
