Reactions of Bis-enamines with Aldehydes - New Synthesis of 1,3-Oxazines and PyridinesIn the presence of phosphoric acid N-alkyl-dipropenylamines react with aliphatic aldehydes to form substituted 1,3-oxazines. With benzaldehyde this reaction does not proceed, but azomethines are formed. N,N-dipropenylaniline with aldehydes also gives azomethines, a dihydropyridine is formed as well. From tripropenylamine and aldehydes substituted pyridines are obtained.
