Abstract

Some new derivatives of 3,5-diaryl-4-imino-5,7,8,9-tetrahydro-3H-chromeno[2,3-d]pyrimidine have been prepared through a condensation reaction of 2-amino-4-aryl-3-cyano-5,6,7,8-tetrahydrobenzo[b]pyrans with triethyl orthoformate in boiling acetic anhydride followed by cyclization with primary aryl amines in the presence of a few drops triethylamine as catalyst in refluxing ethanol. The products were characterized on the basis of IR, 1H-NMR, and 13C-NMR spectral and microanalytical data.
