An organic amine mediated photolytic [1,3]-benzoyl migration of β-benzoyl carbonyl compounds was reported. This migration was achieved by Norrish-Yang cyclization and retro-aldol reaction under black light (365 nm) or visible light irradiation. This photolytic protocol provides an alternative approach to the synthesis of 1,5-dicarbonyl compounds. By chiral primary amine catalysis, a kinetic resolution
报道了有机胺介导的β-苯甲酰基羰基化合物的光解[1,3]-苯甲酰基迁移。这种迁移是通过在黑光(365 nm)或可见光照射下进行的Norrish-Yang环化反应和逆醛醇反应实现的。该光解方案为合成1,5-二羰基化合物提供了另一种方法。通过手性伯胺催化,还发展了动力学拆分以提供对映体富集的1,5-二羰基。
