catalysis and hydrogen atom transfer to achieve the alkylation of 2H-benzothiazoles with alcohols, ethers, lactams, amides and alkane, which features broad substrate scope and excellent functional group compatibility. Notably, alcohols can be used not only as hydroxyalkylating reagents, but also as dehydroxyalkylating reagents in this regulable alkylation protocol. The previous elusive self-photocatalytic
在这里,我们报道了一种温和有效的方法,将自光氧化还原催化和氢原子转移相结合,实现 2 H-苯并噻唑与醇、醚、内酰胺、酰胺和烷烃的烷基化,具有广泛的底物范围和优异的官能团相容性。值得注意的是,醇不仅可以用作羟烷基化试剂,还可以在这种可调节的烷基化方案中用作脱羟烷基化试剂。研究了以前难以捉摸的自光催化机理,并报道了这种催化烷基化的初步结果。
