Abstract

See full text

Methods for producing enantiodefined polycyclic compounds, particularly tetracyclic compounds, are provided. More particularly, synthetic methods for producing biologically active enantiodefined steroidal compositions of both natural (“nat-”) and unnatural (“ent-”) absolute stereochemistry are provided. An exemplary method for manufacturing a tetracyclic compound comprises a step of forming a hydrindane intermediate through coupling of a suitably functionalized enyne with a suitably functionalized alkyne and subsequently performing an intramolecular ring-closing reaction to form the tetracyclic compound. Steroidal compounds obtained by this method and methods of using such steroidal compounds in human and/or animal therapeutics and medicines are also provided.
