Abstract

A second new sulphurcontaining amide, entadamide B, has been isolated from the dry seeds of Entada phaseoloides Merr. together with entadamide A. Entadamide B was characterized by spectroscopic methods as N-(2 hydroxyethyl)-3,3bis(methylthio)propanamide and was synthesized in two steps from propiolic acid.
