Asymmetric synthesis of taxol arid taxotère side chains by enolate hydroxylation

We report an asymmetric synthesis of the taxol and taxotère side chains by hydroxylation of enolates derived from N-substitued methyl 3-amino-3-phenyl propionate with the oxodiperoxymolybdenum (pyridine) (hexamethyl phosphoric triamide) complex (MoOPH). Key words: taxol and taxotère side chains, hydroxylation.
