A novel photochemical approach for the synthesis of phenanthrene derivatives fromlinear 3-aryl-N-(arylsulfonyl) propiolamides via a tandem radical Smiles rearrangement/C–S bonding/Mallory reaction is disclosed. The control experiment results and isolation of the key intermediates give further insight into the reaction mechanism. Gram scale reaction using a flow reactor demonstrated the synthetic potential

A visible light-mediated radical Smiles rearrangement has been achieved using neutral eosin Y as a direct hydrogenatomtransfer (HAT) photocatalyst. Novel N-heterocycles as single diastereomers featuring an isothiazolidin-3-one 1,1-dioxide moiety are directly accessed by this method. A wide range of functional groups can be incorporated in the products by employing diverse aldehydes and N-(hetero)arylsulfonyl
使用中性伊红 Y 作为直接氢原子转移 (HAT) 光催化剂,已经实现了可见光介导的自由基微笑重排。通过这种方法可以直接获得作为具有异噻唑啉-3-one 1,1-二氧化物部分的单一非对映异构体的新型 N-杂环。通过使用不同的醛和 N-(杂)芳基磺酰基丙酰胺,可以在产品中加入多种官能团。转化通过一系列可见光诱导的 HAT、1,4-加法、Smiles 重排、5-endo-trig 环化和反向 HAT 过程进行。高度官能化杂环化合物的初步生物学研究表明,某些合成化合物具有潜在的抗癌活性。
