    摘要: This invention relates to a process for the preparation of 7-hydroxy taxanes of general formula (I) from 7-trialkylsilyl taxanes of general formula (II), wherein R.sub.1 is hydrogen, alkoxy, acyloxy, or alkoxyacetoxy, and Z is a hydrogen atom or a radical of general formula (III), wherein R.sub.2 is an optionally substituted benzyl radical or an R'.sub.2 --O--CO-- radical wherein R'.sub.2 is an alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, bicycloalkyl, optionally substituted phenyl or heterocyclyl radical, R.sub.3 is an aromatic alkyl, alkenyl, alkynyl, cycloalyl, phenyl, naphthyl or heterocyclyl radical and either R.sub.4 is a hydrogen atom and R.sub.5 is a hydroxyl function protecting group, or R.sub.4 and R.sub.5 together form a saturated 5- or 6-membered heterocylic ring. In general formula (II), each R, which are the same or different, is an alkyl radical optionally substituted by a phenyl radical. ##STR1##

    摘要: The present invention relates to a novel process for the preparation of 7-trialkylsilylbaccatin III of general formula: ##STR1## in which the symbols R, which may be identical or different, represent alkyl radicals containing 1 to 4 carbon atoms which are optionally substituted with a phenyl radical, starting with 10-deacetylbaccatin III of formula: ##STR2## In the general formula (I), each of the symbols R preferably represents a straight or branched alkyl radical containing 1 to 4 carbon atoms. Even more particularly, each of the symbols R represents an ethyl radical.
