摘要

本文描述了一种操作简单的由烯烃非对映选择性构造环丙基酮的方法。伪卤化物-SCN被用作无迹助剂，以缓解卤化物中间体带来的消除问题，导致环丙烷歧管中成功地纳入单吸电子基团取代自由基祖细胞。

Thiocyanate: A Visible Light Driven Traceless Auxiliary for Stereoselective Cyclopropyl Ketone Construction

An operationally simple method for the diastereoselective construction of cyclopropyl ketones from olefins is hereby described. The pseudohalide -SCN is used as a traceless auxiliary towards assuaging the elimination problem posed by halide intermediates, leading to the successful incorporation of single electron withdrawing group substituted radical progenitors in the cyclopropanation manifold.
