title: Moluccensins A-G, phragmalins with a conjugated C-30 carbonyl group from a Krishna mangrove, Xylocarpus moluccensis.
abstract: Seven new phragmalins with a C-30 carbonyl moiety, named moluccensins A-G (1-7), among which moluccensins A-F, possessing a Delta(8,14) double bond, and moluccensin G (7), containing conjugated Delta(8,9) and Delta(14,15) double bonds, were isolated from the seeds of an Indian mangrove, Xylocarpus moluccensis. The structures of these compounds were established on the basis of single-crystal X-ray diffraction analysis and spectroscopic data. This is the first report of phragmalins with a conjugated C-30 carbonyl group.
