A double dearomatization of dyads consisting of 1-sulfonyl-1,2,3-triazoles and 3-aryl-5-methoxyisoxazoles was applied for the efficient synthesis of nonfused 1H-1,3-diazepines. The plausible mechanism of the cascade reaction includes transformation of the 1,2,3-triazole to rhodium azavinyl carbene, the Z-selective hydride shift to form the 1-azabuta-1,3-diene moiety, rhodium-catalyzed ring contraction of the isoxazole to azirine, and pseudopericyclic four-atom ring expansion of the azirine. The synthetic utility and antiproliferative activity of the 1,3-diazepines obtained have been demonstrated.

铑催化 1,2,3-三唑-异恶唑二元组的双重脱芳构化:非稠合 1H-1,3-二氮杂卓的合成



由1-磺酰基-1,2,3-三唑和3-芳基-5-甲氧基异恶唑组成的二元体的双重脱芳构化被应用于非稠合1 H -1,3-二氮杂卓的有效合成。级联反应的合理机制包括 1,2,3-三唑转化为铑氮杂乙烯基卡宾, Z-选择性氢化物位移形成 1-azabuta-1,3-二烯部分,铑催化的环收缩异恶唑变为氮丙啶,以及氮丙啶的假周环四原子环扩展。所获得的1,3-二氮杂卓的合成用途和抗增殖活性已得到证实。
