The reaction of 19 - prepared efficiently from 16 - with DDQ affords 22.This epoxide may serve as a model compound to investigate the biosynthesis of sporidesmins, e.g. 1 and 2.

N-Hydroxytryptophan derivatives have been synthesized via two routes.In one procedure, the indole-3-pyruvate oximes 14b,c were reduced with trimethylamine-borane in the presence of ethanolic HCl to give 18 (Scheme III); aminolysis of the latter afforded 1
