Absolute structures of stemona-lactam S and tuberostemospiroline, alkaloids from stemona tuberosa

Chem Pharm Bull (Tokyo). 2013;61(10):1085-9. doi: 10.1248/cpb.c13-00454.

Abstract

A new alkaloid, stemona-lactam S, and a known alkaloid, tuberostemospiroline, were isolated from the roots of Stemona tuberosa LOUR. (Stemonaceae). Their structures and absolute stereochemistry were established by X-ray crystallography and vibrational circular dichroism.
