, (2008/06/13)
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 R1 is an optionally substituted benzoyl, thenoyl or furoyl radical or a radical R2 --O--CO, where R2 is an alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, bicycloalkyl, optionally substituted phenyl, or heterocycl radical, and R3 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
Process for preparing taxane derivatives
-
, (2008/06/13)
Method of preparing taxane derivatives of general formula (I) by esterification of protected baccatine III or 10-deacetyl-baccatine 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.

A new route for semisynthetic docetaxel, 1, is desribed using 2-monosubstituted-4-phenyl-1,3-oxazolidine-5-carboxylic acids in esterification of 7,10-O-diTroc-10-desacetylbaccatin III (4).Subsequent deprotection of esters 10(+10') afforded title compound 1 without removal of the Boc group.
