  Synthesis of anabasine-containing aminomethyl derivatives of 6-hydroxyaurones

  摘要：

  uAminomethylation of aurones was studied by using anabasine. The reaction in the case of 6-hydroxyaurones was shown to selectively provide 7-aminomethyl-6-hydroxyaurones, while 5-aminomethyl-6-hydroxy-7-methylaurones could be obtained by transamination of 5-dimethylaminomethyl derivatives of 6-hydroxy-7-methylaurones in the presence of anabasine.

  Aminomethylation of 7-substituted 6-hydroxyaurones was studied using primary and secondary amines. In the case of 6-hydroxy-7-methylaurones, their 5-dialkylaminomethyl derivatives or 7-benzylidene-3,4-dihydro-2Н-furo[3,2-g][1,3]benzoxazin-6(7Н)-ones were formed. The aminomethylation reaction of 6,7-dihydroxyaurones produced only 5-aminomethyl derivatives.
