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).

Novel 2-aryl-1H-perimidine compounds, which are useful as immunosuppressive agents, are described herein. The compounds are prepared by the condensation of 1,8-diaminonaphthalene with an appropriate acyl compound.
