coumarins and chromenes via conjugate addition represents a relatively unexplored and challenging task. To address this issue, herein, we report a new and general copper (I) catalyzed dearomative borylation process to synthesize boron-containing oxacycles. In this report, the borylation of coumarins, chromones, and chromenes comprising functional groups, such as esters, nitriles, carbonyls, and amides, has
通过共轭加成对香豆素和色烯进行脱芳香硼化是一项相对未经探索且具有挑战性的任务。为了解决这个问题,我们在此报告了一种新的通用铜(I)催化脱芳硼化工艺来合成含硼氧杂环化合物。在本报告中,已经实现了包含酯、腈、羰基和酰胺等官能团的香豆素、色酮和色烯的硼基化。此外,该方法还生成不同类别的潜在硼基类维生素A,包括具有恶二唑和花青素基序的类维生素A。硼酸化的氧杂环化合物可以作为合适的中间体来生成化合物库。
