Diels-Alder cycloadditions of highly substituted cyclohexadienes derived from rhodium-mediated [2 + 2 + 2] cyclizations are reported. Reactive heterodienophiles, including singlet oxygen ((1)O(2)), 4-substituted-1,2,4-triazoline-3,5-diones (TADs), and aryl- and acylnitroso compounds were employed, yielding novel heterocyclic products.
报道了铑介导的[2+2+2]环化反应衍生的高取代环己二烯的 Diels-Alder 环加成反应。使用了反应性杂二烯亲电试剂，包括单线态氧((1)O(2))、4-取代-1,2,4-三唑啉-3,5-二酮(TADs)和芳基和酰基亚硝化合物，生成了新型杂环产物。
