An efficient and operationally simple approach to complex cis-hexahydroindanes is reported. Upon Birch reduction of unprotected, C4-alkylated tetrahydroindanols and electrophilic trapping of the tetrasubstituted enolate, cis-fused products are formed with a new stereogenic quaternary carbon. The reaction is convergent, completely diastereoselective, and shows a broad scope with regard to the electrophile
