Abstract
1 H n.m.r. spectral analysis shows that the β-hydroxyleucine portion of the peptide alkaloids frangulanine and discarine A and B possess and erythro-configuration; stereochemical analysis of frangulanine by enzymic oxidation of its product of reduction and subsequent hydrolysis reveals the subunit to be of the L-erythro-β-hydroxyleucine-type.Keywords
