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

Kavala, Veerababurao,Lin, Chunchi,Kuo, Chun-Wei,Fang, Hulin,Yao, Ching-Fa

, p. 1321 - 1329 (2012)

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.
