Abstract
ABSTRACT The erythro8-O-4′ neolignan IIIb was synthesized and was found to have identical 1H and 13C NMR characteristics to a neolignan reported as a component of the roots of Nardostachys jatamansi. The NMR spectral characteristics of compound IIIb were also identical with those of a neolignan previously obtained from the roots of Piper capense, for which the unlikely 8-O-3′ structure IVa had been proposed. Two further erythro 8-O-4′ compounds IIIc and IIId were prepared, and their assigned 13C NMR signals were consistent with those of IIIb. At this time, there appears to be no evidence for the existence of 8-0-3′ neolignans as plant extracts.
