摘要
Sinenxan H [2 alpha,14 beta-diacetoxytaxa-4(20),11-diene-5 alpha, 10 beta-diol, 1] was isolated from the heartwood of Taxus cuspidata, for the first time from natural sources. Compound 1 was found to be readily converted into 2 alpha-acetoxytaxa-4(20),10,12(18),13-tetraen-5 alpha-ol (2), the first example of a taxane with 10,11- and/or 13,14-double bond(s) and a conjugated triene system, in CDCl3.
