  • Taxoids, their preparation and the pharmaceutical compositions which contain them
    Patent number: 5556877
    Abstract: This invention relates to taxoids of general formula (I), their preparation and the pharmaceutical compositions which contain them. The products of general formula (I) have notable antitumoral properties. In the general formula (I),Ar represents an aryl radical,R represents a hydrogen atom or an acetyl or alkoxyacetyl radical,R.sub.1 represents a benzoyl radical or a radical R.sub.2 --O--CO-- in which R.sub.2 represents an alkyl, alkenyl, cycloalkyl, cycloalkenyl, bicycloalkyl, phenyl or heterocyclyl radical, andR.sub.3 represents an alkyl, alkenyl, cycloalkyl, cycloalkenyl, bicycloalkyl, optionally substituted aryl (with the exception of unsubstituted phenyl) or heterocyclyl radical.
