Generation of pyrrolo[2,3-d]pyrimidines. Unexpected products in the multicomponent reaction of 6-aminopyrimidines, dimedone, and arylglyoxal

Quiroga, Jairo,Acosta, Paola A.,Cruz, Silvia,Abonía, Rodrigo,Insuasty, Braulio,Nogueras, Manuel,Cobo, Justo

experimental part, p. 5443 - 5447 (2010/10/21)

A series of 6-aryl-5-(1-cyclohexen-1-yl)pyrrolo[2,3-d]pyrimidines 9a-q were obtained by the three-component reaction between 6-aminopyrimidines 6, 7, 8, dimedone 2, and arylglyoxal 5a,b. The unexpected cyclization process was established by NMR and X-ray diffraction measurements.
