  • New Aspects of Stetter Reaction and Cross-Benzoin Reaction Catalyzed by Thiazolium Salts

抄録

Thiazolium-catalyzed reactions consisted with Stetter reaction and benzoin condensation showed us new aspects: 1) formation of quaternary carbon with Stetter reaction and 2) selective cross-benzoin condensation. The construction of quaternary carbon with Stetter reaction was accomplished with the intramolecular reaction using salicylaldehyde derivatives as substrates. This reaction was carried out with good yield under mild conditions. And also this reaction is the first example of the construction of quaternary carbon with Stetter reaction. We also found that the combination of aromatic aldehyde and aliphatic aldehyde is very important for the selective synthesis of desired acyloin product in the thiazolium salts-catalyzed cross-benzoin reaction.
