Abstract

Synthetically important, cis-fused hydrindane skeleton having quaternary angular stereogenic centers was selectively furnished by intramolecular Diels-Alder reaction of ester-tethered precursor via endo transition state. The reaction was applicable for a construction of the steroidal BCD ring system with cis-hydrindane framework.
