AMINOMETHYLATION OF HYDROXYACETONAFTONES
Aminomethylation of hydroxyacetonafton primary and secondary amines with excess of formaldehyde has been carried out. It revealed that the use of secondary amines 1-hydroxy-2- and 1-hydroxy-4-acetonaftone makes it possible to obtain directly the aminomethyl derivatives, and while amines 1-hydroxy-2-acetonaftones do not expose to the Mannich reaction with primary aromatic amines, 1-hydroxy-4-acetonaftones with primary aromatic amines […]
