摘要：
The regioisomeric 6-hydroxy-4-methyl- and 4-hydroxy-6-methylaurones were synthesized. Aminomethylation by the action of aminals of secondary amines was investigated. It was shown that the reaction proceeds selectively with the formation of 7-aminomethyl-6-hydroxy-4-methyl- and 5-aminomethyl-4-hydroxy-6-methylaurones, respectively. The use of an excess of the aminals allows to obtain 5,7-bis(aminomethyl) derivatives of 6-hydroxy-4-methylaurones.
