    Abstract: Novel taxoids of general formula (I), wherein R is a substituted alkyl radical or an alkenyl, alkynyl, cycloalkyl, optionally substituted cycloalkenyl or phenyl radical, or an aromatic 5- or 6-membered heterocyclic radical; and Z is a hydrogen atom or a radical of general formula (II), wherein R.sub.1 is an optionally substituted benzoyl, thenoyl or furoyl radical or a radical R.sub.2 --O--CO, where R.sub.2 is an alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, bicycloalkyl, optionally substituted phenyl, or heterocycl radical, and R.sub.3 is an aromatic heterocyclic, alkyl, alkenyl, alkynyl cycloalkyl, phenyl or naphthyl radical. The novel products of general formula (I), wherein Z is a radical of general formula (II), have remarkable antitumoral activity. ##STR1##

    Abstract: This invention relates to a process for preparing taxoid derivatives of formulae II and XI: ##STR1## in which Ar represents an aryl radical; R.sub.1 represents a benzoyl radical or a radical R.sub.2 --O--CO-- in which R.sub.2 represents an unsubstituted or substituted alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, bicycloalkyl, phenyl, or saturated or unsaturated heterocyclic radical; R.sub.3 represents an unsubstituted or substituted alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, bicycloalkyl, saturated or unsaturated heterocyclic, or aryl radial, but not a phenyl radical; R.sub.4 represents a hydrogen atom and R.sub.5 represents a hydroxyl-protecting group or R.sub.4 and R.sub.5 together form a heterocyclic group; G.sub.1 represents a hydroxyl-protecting group; and G.sub.2 represents an acetyl radical or hydroxyl-protecting group;by electrolytically reducing a protected taxoid compound in an electrolyte comprising a quaternary ammonium salt which is soluble in an organic solvent or in an aqueous/organic mixture at a controlled potential.
