Abstract

Eleven taxoids were isolated from needles of the Japanese yew, Taxus cuspidata Sieb. et Zucc., one of them being a new compound whose structure was established as5α-cinnamoyl-9α,10β,13α-triacetoxy-11(15→1)abeotaxa-4(20),11-dien-15-ol (7-deactoxytaxuspine J) on the basis of a spectroscopic analysis. Its relative stereochemistry is proposed from the results of a NOESY experiment.
