Abstract
Three new 14beta-benzoyloxy taxoids containing an oxetane ring, namely, 14beta-benzoyloxybaccatin IV (1), 14beta-benzoyloxy-13-deacetylbaccatin IV (2), and 14beta-benzoyloxy-2-deacetylbaccatin VI (3), have been isolated from the leaves and stems of Taxus chinensis. Their structures were elucidated on the basis of 1D and 2D NMR spectroscopic data.
