Highly enantioselective organocatalytic construction of spirochromans containing a tetrasubstituted stereocenter was developed. Intramolecular oxy-Michael addition was catalyzed with a bifunctional cinchona alkaloid thiourea catalyst. A variety of spirochroman compounds containing a tetrasubstituted stereocenter were obtained with excellent enantioselectivities of up to 99% enantiomeric excess. The reaction was applied to the asymmetric formal synthesis of (-)-(R)-cordiachromene.
