Abstract

<jats:title>Abstract</jats:title><jats:p>A side‐cut of the industrial purification of an extract of yew needles afforded eight new taxoids, including two derivatives of taxine A, the 7‐O‐acetyl‐ (2) and the 2‐deacetyl‐ (3) derivatives. The new structures were established by spectroscopic methods, and some unusual features of the <jats:sup>1</jats:sup>H‐NMR spectra of taxine A and its derivatives are discussed.
