G. Appendino et al., THE CHEMISTRY AND OCCURRENCE OF TAXANE DERIVATIVES .8. NEW OXETANE-TYPE TAXANES FROM TAXUS-WALLICHIANA ZUCC, Journal of the Chemical Society. Perkin transactions. I, (14), 1993, pp. 1563-1566
The needles of Taxus wallichiana Zucc. gave the novel oxetane-type tax
ane diterpenoids 2 and 5, whose structures have been established on th
e basis of spectroscopic data and chemical reactions. The acid-catalys
ed rearrangement of 10-deacetylbaccatin III has been investigated.
