  One-Pot, Diversity-Oriented Synthesis of Aryl-Substituted Benzoxacycles Including Benzofuran, Coumarin, and Benzoxazepine

  摘要：

  A one-pot method for the synthesis of benzoxacycles including benzofuran, coumarin, benzoxazepine, and benzoxazocine from a common synthetic intermediate was established. Benzoxacycles are privileged structures in medicinal chemistry and have featured in several clinically used drugs. The synthesis of a benzofuran containing an aryl substituent was accomplished using potassium carbonate and sodium hydride. The one-pot synthesis of coumarin was also carried out using trans-decalin as the solvent. The optimized conditions for the one-pot synthesis of benzoxazepine can also be applied to the synthesis of benzoxazocine.

  by the visible-light-induced acylation/cyclization of alkynoates with various acyl oxime compounds in acetonitrile. The difunctionalization of carbon–carbon triple bonds precedes the generation of iminyl radicals, which is followed by the formation of acyl radicals. The acyl radicals then attack the carbon–carbon triple bonds, followed by 5-exo-trig cyclization and 1,2-ester migration. This strategy

  描述了一种以氮为中心的自由基介导的碳-碳键断裂策略来合成功能化的 3-酰基香豆素。该策略是通过可见光诱导的炔酸酯与乙腈中的各种酰基肟化合物的酰化/环化来实现的。碳-碳三键的双官能化先于亚氨基自由基的产生，然后是酰基自由基的形成。然后酰基自由基攻击碳-碳三键，然后进行 5 -exo-trig环化和 1,2-酯迁移。该策略具有广泛的底物适应性和良好的取代基耐受性。
