Abstract
Conformational isomerism has been demonstrated for the four major naturally occurring procyanidins, and the phenomena have been interpreted in terms of two different forms of restricted rotation about the interflavan bond; based on these observations structures of opposite helicity are proposed for the two principal types of procyanidin polymer found in Nature.This publication has 0 references indexed in Scilit:
