Iodine catalyzed one-pot synthesis of flavanone and tetrahydropyrimidine derivatives via Mannich type reaction

A variety of functionalized flavanone derivatives and tetrahydropyrimidine derivatives were achieved under remarkably mild conditions. The combination of good to excellent yields, a simple work-up, and the high compatibility of functional groups makes this an attractive synthetic approach to access flavanone and tetrahydropyrimidine derivatives.
