Amidyl radicals 2 generated from tributylstannane mediated homolysis of O-benzoyl hydroxamic acid derivatives 6a-g undergo alkyl mode 5-exo cyclisation to give mixtures of cis and trans N-acyl pyrrolidinones (d.e. = 54-74%). The efficiency of the process was found to be dependant upon the steric and electronic nature of the nitrogen substituent.
在三丁基锡烷介导的O-苯甲酰羟胺酸衍生物6a-g的均裂过程中生成的Amidyl自由基2,通过烷基方式5-外环化,生成了顺反N-酰基吡咯烷酮的混合物(d.e. = 54-74%)。研究发现,该过程的效率取决于氮原子的取代基的立体和电子性质。
