Advanced Molecular Transformations by Organocatalysts



The development of organic molecules which function as a catalyst has been extensively investigated to achieve selective and efficient transformation of organic molecules. Brønsted acids and bases are commonly employed as the catalyst in synthetic organic chemistry. To aim at their functionalization, axially chiral phosphoric acids and axially chiral guanidine bases have been developed as chiral Brønsted acid and base catalysts, respectively. A variety of optically active compounds has been synthesized through the development of highly stereoselective reactions using these catalysts.

Targeted Application(s)/Industry

The development of chiral Brønsted acid and base catalysts has been accomplished as recoverable and reusable organocatalysts and highly stereoselective molecular transformations have been established using these catalysts. The present methodology is applicable to process chemistry in preparing medicines and relevant compounds on the basis of the selective and efficient molecular transformations thus developed with reduction of the waste material.
