hybrid compounds-the taxosteroids-possessing carbon frameworks incorporating moieties characteristic of both taxanes (such as ABrings) and steroids (i.e., CD system and side chain). This tandem cyclization is highly stereoselective, allowing the one-step formation of the bicyclo[5.3.1]undecene system characteristic of taxol. In this work we describe the scope and limitations of such cyclizations.

The present invention relates to a process of obtaining taxosteroids and precursors thereof from the hydrindane bicyclic ring system. The compounds have a tetracyclic system which combines the structural characteristics of taxanes, such as the bicyclo[5.3.1]undecane system (cycles A and B), fused to a six-membered ring (C), and of steroids, such as the CD bicycle, the A ring and the side chain (Sc). The process of preparing the compounds and their application as compositions with pharmacological properties of interest are described.
