Abstract
Reaction of cinnamonitriles with 3-aminophenol or resorcinol gave the corresponding benzopyran derivs. 2,7-Diamino-4-phenyl-4H-benzopyran-3-carbonitrile (I) reacted with benzaldehyde to yield the monobenzylideneamino deriv. Also, reaction of I with benzenesulsulfonyl chloride gave 2-amino-3-cyano-4-phenyl-7-phenylsulfonylamido-4H-benzopyran which, in turn, underwent some reactions to produce new benzopyrano[6,5-d]pyrimidine derivs.
Извините, пожалуйста, за несколько глумливый тон, просто семья Нифантьевых широко известна в некоторых узких химических кругах, и у одного из них я имел необыкновенное счастье работать.
