A new photolabile linker enabling nucleophilic cleavage of a carboxyl functionality upon irradiation with UV light (> 290 nm) was developed. When the photocleavage is carried out in the presence of primary or secondary amines, amides are obtained in high yields and purities, while the intramolecular version of this reaction leads to heterocycles via a cyclorelease mechanism.
开发了一种新的光敏连接子,可以在紫外光照射下(> 290 nm)使羧基功能团进行亲核裂解。当在一级或二级胺存在下进行光裂解时,可以获得高产率和高纯度的酰胺,而该反应的分子内版本通过循环释放机制生成杂环。
