Pyridines and Quinolines from 1,3-Dichloro-Trimethinecyanines Pyrimidine and Quinazoline from Azacyanine
A new synthesis of 2,4-bis(dialkylamino)-pyridines and quinolines is reported. Starting from primary aryl amines or aliphatic imines a mechanism via ynamine-amidines is followed if the cyanine Ia is used as reagent. When the cyanine is substituted, (I.R. ≠ H) it reacts well in high dilution conditi...
