Historically, general convergent syntheses of medium ring heterocycles have been difficult to develop. Herein, we describe the synthesis of five classes of heterocycles: dihydrodibenzo[b,f]azepine, -oxocine, and -thiocine and dibenzo[b,f]azepine and -oxepine using a strategy of alkylation followed by highly selective intramolecular Heck arylation reaction. The hetero-tricyclic compounds were available
从历史上看,中环杂环的一般收敛合成一直很难开发。在这里,我们描述了五类杂环的合成:二氢二苯并[b,f] a庚因,-oxocine和-thiocine和二苯并[b,f] a庚因和-oxepine使用烷基化策略,然后进行高度选择性的分子内Heck芳基化反应。从可商购的起始原料开始,仅在两个步骤中可获得杂三环化合物。
