Two new tryptamine-derived alkaloids from Chimonanthus praecox f. concolor
摘要:
A new pyrrolidinoindoline-type alkaloid, CPC-1, and a new tryptamine-derived dimeric alkaloid, CPC-2, were isolated from the seeds and rinds of Chinionanthus praecox f. concolor. The structure including the absolute configuration of CPC-1 was determined by chiral total synthesis. CPC-2 has a unique hexahydropyrroloquinoline skeleton. (c) 2006 Elsevier Ltd.

Two new tryptamine-related alkaloids, chimonamidine and chimonanthidine, were isolated from the seeds of Chimonanthus praecox Link. and their structures including absolute configuration were elucidated by spectroscopic analysis and biomimetic total synthesis from tryptamine.
