Aminoamidines. 5. Synthesis and acetylation of N,N1,N2-triaryl-substituted ?-aminoamidines
摘要:
Triaryl-substituted beta-aminoamidines were obtained by the reaction of alpha,beta-unsaturated N-arylimidoyl chlorides with arylamines. Acylation of the products gave the products from monosubstitution at the beta-amino group. Triaryl-substituted beta-aminomidines react with phosgene and with oxalyl chloride to form 4-aryliminoperhydropyrimidin-2-ones and 5-aryliminoperhydro-1,4-diazepine-2,3-diones, respectively.
