The preparation of a homochiral 7-nor taxoid C-ring framework, to be used in an A+C approach for the synthesis of low oxygenation pattern taxoids with an exocyclic olefin at C(4)–(20) and oxygenation at C(14), is described. Retrosynthetic analysis associated with the preparation of 3 has been designed around the targets 11 and 15 which could be produced by functional group manipulation starting from
