  摘要：

  Photolysis of a series of p-substituted phenyl azides (p-X-C6H4N3; X = CO2Me, CO2Et, CN, CF3, SO2NH2, CO2CHPh2, COMe, CHO, and NO2) in 1:1 (nu/nu) THF-water solution produces, in the majority of cases, a 5-substituted-3H-azepine-2-one. In a like manner, 3H-azepin-2-one-3-carboxylates can be prepared from 5-substituted-2-azidobenzoates, providing the 5-substituent is electron-withdrawing.3H-Azepin-2-one mono- and di-carboxylic acids, the former in admixture with decarboxylated material, and 6H-azepino[2,1-b]quinazolin-12-ones, are obtained by irradiation of 2-azidobenzoic acid and of 5-azidoisophthalic acid, respectively. The mode of formation of the azepino-quinazolinones is discussed.

  photopromoted, metal-free transannulation of phenyl azides for the synthesis of DNA-encoded seven-membered rings. The transformation is efficiently achieved through a skeletal editing strategy targeting the benzene motif coupled with a Reversible Adsorption to Solid Support (RASS) strategy. A variety of valuable DNA-encoded seven-membered ring compounds, including DNA-encoded 3H-azepines, azepinones, and

  在本报告中，我们提出了一种光促进、无金属的苯基叠氮化物转环反应，用于合成 DNA 编码的七元环。该转化是通过针对苯基序的骨架编辑策略与可逆吸附到固体支持物（RASS）策略相结合而有效实现的。现在可以获得多种有价值的 DNA 编码的七元环化合物，包括 DNA 编码的 3H-氮杂卓、氮杂酮和非天然氨基酸。至关重要的是，这种与 DNA 兼容的方案也可用于引入复杂分子，例如 Lorcaserin 和 Betahistine。将容易获得的苯环选择性地转化为高价值的七元环，为构建多样化和类药物的 DNA 编码库提供了一条有前途的途径。
