An efficient synthesis of novel hexahydropyrido[2,3-d]pyrimidine derivatives from (arylmethylidene)pyruvic acids =(3E)-4-aryl-2-oxobut-3-enoic acids in aqueous media

Balalaie, Saeed,Abdolmohammadi, Shahrzad,Soleimanifard, Bita

, p. 932 - 936 (2009)

A series of new hexahydropyrido[2,3-d]pyrimidine derivatives 3 were synthesized by the cyclo-condensation reaction of (arylmethylidene)pyruvic acids (=(3E)-4-aryl-2-oxobut-3-enoic acids) 1 and 6-aminouracils (=6-aminopyrimidine- 2,4(1H,3H)-diones) 2 in H
