Paclitaxel analogs modified in ring C: Synthesis and biological evaluation

Lead tetracetate oxidation of 6α-hydroxy-7-epi-paclitaxel lends to C-nor-paclitaxel and C-seco-paclitaxel derivatives. Tetrpropylammonium perruthnate (TPAP) oxidation of a 6α-hydroxy-7-epi-paclitaxel derivative leads to a 6-formyl-C-nor-paclitaxel derivative. Reaction of a 6α-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.

Synthesis and Biological Evaluation of Paclitaxel Analogs Modified in Ring C

Both 7-deoxy-7α-azidopaclitaxel (6) and 7-deoxy-Δ6,7-paclitaxel (4) can be prepared from paclitaxel-7-O-triflate (2b).Oxidation of 7-deoxy-Δ6,7-paclitaxel with dioxirane yields the epoxide 7, while oxidation with osmium tetroxide yie
