An Improved One-Pot Method for the Preparation of 2-Substituted 1H-Perimidines
摘要:
2-substituted H-1-perimidines are readily prepared, in high yields, by refluxing a mixture of sodium pyrosulfite, an aldehyde, and 1,8-diaminonaphthalene in aqueous ethanol or N,N-dimethylformamide. The method is of wide applicability except from araldehydes bearing a strong electron-withdrawing group (-CN, -NO2).

2-substituted perimidines 3(a g) were prepared from an acid-catalyzed reaction of 1,8-diaminonaphthalene with carboxylic acids using microwave irradiation. Addition of these perimidines to 1-chloromethyl benzotriazole in the presence of the sodium amide under reflux conditions gave benzotriazole-substituted perimidines 5(a-f). Yields of these products following recrystallization from water were of the order of 60-65%. IR and (HNMR)-H-1 spectra and elemental analysis were used for identification of these compounds.
