A novel route for a SnCl2-promoted tandem reduction, ammonolysis, condensation, and deamination reaction which uses nitrile and 2-nitro-N-phenylbenzenesulfonamide/N-(2-nitrophenyl)benzenesulfonamide to synthesize derivatives of benzothiadiazine/1-(phenylsulfonyl)-1H-benzimidazole has been developed. The method features convenient operation and good functional group tolerance. In addition, it employs
SnCl 2促进串联还原、氨解、缩合和脱氨反应的新路线以腈和2-硝基-N-苯基苯磺酰胺/ N- (2-硝基苯基)苯磺酰胺合成苯并噻二嗪/1-(苯磺酰基)衍生物开发了-1H-苯并咪唑。该方法操作方便,官能团耐受性好。此外,它采用不敏感且廉价的 SnCl 2 / i -PrOH 作为反应试剂,为合成重要的药学靶标提供了直接途径。
