Daphenylline, a new alkaloid with an unusual skeleton, from Daphniphyllum longeracemosum

Org Lett. 2009 Jun 4;11(11):2357-9. doi: 10.1021/ol9007958.

Abstract

A new alkaloid, daphenylline (1), with an unprecedented rearranged 22-nor-calyciphylline skeleton, was isolated from the fruits of Daphniphyllum longeracemosum. Its structure and stereochemistry were elucidated on the basis of spectroscopic and computational approaches. A plausible biosynthetic pathway of 1 was also proposed.
