A Stereochemical Model of the Veratrum Alkaloids

A stereoselective synthesis begining from the tetracyclic isoxazolidine 3 gave an inactive model (2) of rings D-F of the hypotensive Veratrum alkaloids (1).Cleaving, N-demethylating, and epimerizing 3 gave the amino alcohol 5a.Diazotizing 5a afforded lact
