- Abstract
The reaction of 2-aminomethylaniline with 1,3-dicarbonyl compounds gives a series of 1,2,3,4-tetrahydroquinazoline derivatives. A ring-chain tautomeric equilibrium of the type enamine-1,2,3,4-tetrahydroquinazoline is observed in solutions of these compounds and its position depends of the structure of the starting dicarbonyl component and the solvent polarity.
