    摘要: Method for the preparation of β-phenylisoserine derivatives of general formula (I) involving the action of an anhydride and hydrogen with a product of general formula (II). The products of general formula (I) are especially useful in the preparation of taxoids having outstanding antitumour properties. In general formulae (I) and (II), Ar is an aryl radical, Ph is a phenyl radical or an optionally substituted α or β-naphtyl, R is a hydrogen atom or an alkyl radical optionally substituted by a phenyl radical and R1 is an optionally substituted phenyl radical or a R2-O radical wherein R2 is an alkyl, alkenyl, cycloalkyl, phenyl or heterocyclyl.

    摘要: Method of preparing taxane derivatives of general formula (I) by esterification of protected baccatine III or 10-deacetylbaccatine III by means of an acid of general formula (VII), deprotection of the side chain and elimination of the hydroxy function protection groupings. In general formulae (I) and (VII): Ar stands for aryl, R is hydrogen or acetyl, R1 is benzoyl or R2-O-CO- in which R2 is alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, bicycloalkyl, phenyl or heterocyclyl, and R3 is hydrogen, alkoxy, optionally substituted aryl.

    摘要: Method of preparing taxane derivatives of formula (I) by esterification of protected baccatine III or 10-deacetylbaccatine III by means of an acid of formula (VII), elimination of protection groupings and acylation of the amine function of the side chain. The products of formula (I) have remarkable antitumor and antileukemia properties. In formulae (I) and (VII): Ar stands for aryl, R is hydrogen or acetyl, R1 is a benzoyl radical or an R2-O-CO- radical in which R2 is alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, bicycloalkyl, phenyl or heterocyclyl, R3 is a trihalomethyl radical or phenyl substituted by a trihalomethyl radical, R4 is a hydrogen atom or is the same as R1.
