Abstract A collection of yew needles afforded a taxane diester characterized by an additional bond between C-3 and C-11. The structure was elucidated by spectral methods, and further confirmed by synthesis from a known taxane derivative. A general procedure for the photocyclization of taxicins is reported.

Highly cytotoxic 7-deoxypaclitaxel analogues are obtained by a semisynthesis starting from taxine—the most abundant naturally occurring taxane diterpene fraction.
