Lead tetracetate oxidation of 6 alpha-hydroxy-7-epi-paclitaxel leads to C-nor-paclitaxel and C-seco-paclitaxel derivatives. Tetrapropylammonium permthenate (TPAP) oxidation of a 6 alpha-hydroxy-7-epi-paclitaxel derivative leads to a 6-formyl-C-nor-paclitaxel derivative. Reaction of a 6 alpha-O-trifluoromethanesulfonyl-7-epi-paclitaxel derivative with DMAP yields a 20-O-acetyl-4-deacetyl-5,6-dehydro-6-formyl-C-nor-paclitaxel derivative. C-nor-paclitaxel analogs are less active than paclitaxel. (C) 1997 Elsevier Science Ltd.
