摘要:
Taxol and 10-deacetyltaxol are prepared from a compound of formula: ##STR1## in which R' represents acetyl or 2,2,2-trichloroethoxycarbonyl radical, by removal of the t-butoxycarbonyl radical, benzoylation of the amine product obtained, and removal of the 2,2,2-trichloroethoxycarbonyl group(s).
