Diaza-(4 + 3) cycloadditions of putative diaza-oxyallyl cationic intermediates and cyclic dienes are reported as a method for the 1,4-diamination of cyclic dienes. This reaction was entirely selective for diamination and provided cycloadducts in good to excellent yield.
据报道,假定的二氮杂-氧基烯丙基阳离子中间体和环二烯的重氮-(4 + 3)环加成作为环二烯的1,4-胺化的方法。该反应对于金属化是完全选择性的,并以良好至优异的产率提供了环加合物。
