Development of a catalytic enantioselective intramolecular Stetter reaction: catalyst development and synthetic applications
… enantioselective intramolecular Stetter reaction has been developed. The process involves direct conversion of an aldehyde into a chiral acyl anion equivalent and its addition into a pendant electron-deficient olefin. The development of chiral bicyclic nucleophilic carbene …

The Stetter reaction : synthesis of complex spiro Bis-indanes and studies on quaternary centre formation
This work covers recent advances in the Stetter reaction, including two novel domino Stetter reactions and preliminary studies on quaternary center formation via the intermolecular Stetter reaction. The N-heterocyclic carbene (NHC) catalyzed domino Stetter-aldol-Michael dimerization of o-formyl …

Preparation of Novel Carbenes and their Catalytic Application to the Cross-Benzoin, Aza-Benzoin and Stetter Reactions
… (BACs) generated in situ were screened in the Stetter reaction. Among those tested, bis(diethylamino)cyclopropenylidene (EtBAC) was found to be the most efficient BAC catalyst for the Stetter reaction. EtBAC was also found to be superior to common NHCs in reactions with β-alkyl ketone acceptors …
