Chiral quaternary carbon-containing bicyclic compounds possessing carbonyl functionalities were efficiently synthesized through asymmetric intramolecular aldol reactions with organocatalysts. Bicyclo [3.3.0] and [3.4.0] systems were constructed with a diamine catalyst, while bicyclo [4.3.0] and [4.4.0] skeletons were prepared by an acylsulfonamide type catalyst.
