A feasible protocol that uses atomic groups (KSCN, KSeCN, and NH2CN), o-bromobenzoyl hydrazides, and formyls as reaction factors to synthesize N-fused 1,2,4-triazole with benzothiazides, benzoselenazinones, and quinazolinones was proposed. The method overcomes the lengthy multistep synthesis, narrow substrate scope, and toxicity challenge induced by the use or production of hazardous substances. It
提出了一种可行的方案,使用原子团(KSCN、KSeCN 和 NH 2 CN)、邻溴苯甲酰肼和甲酰作为反应因子,合成 N-稠合 1,2,4-三唑与苯并噻嗪、苯并硒嗪酮和喹唑啉酮。该方法克服了由使用或生产有害物质引起的冗长的多步合成、狭窄的底物范围和毒性挑战。它还可以开发稠合杂环硒和喹唑啉酮衍生物。它们的荧光性能进一步证明了该方法的实用性。
