This study describes a visible-light-induced cascade reaction for preparing cyanoalkyl-containing polyheterocycles initiated by the photoinduced radical addition of N-arylacrylamide derivatives using cyclic oxime esters as sources followed cyanoalkyl-mediated cyclization. protocol features outstanding functional group compatibility, providing variety desired phenanthridine in moderate to good yields. Moreover, application microflow technique enhanced these reactions compared with equivalent batch reaction, significantly reducing times 10 min.

Radical reactions are powerful in creating carbon–carbon and carbon–heteroatom bonds. Designing one-pot radical with cascade transformations to assemble the cyclic skeletons two new functional groups is both synthetically operationally efficient. Summarized this paper recent development of involving addition cyclization dienes, diynes, enynes, as well arene-bridged arene-terminated compounds for preparation difunctionalization compounds. Reactions carried out initiators, transition metal-catalysis, photoredox, electrochemical conditions included.

Abstract We have developed a visible‐light‐mediated synthesis of 3‐arylsulfonylated thioflavones using an in situ‐activation strategy. The reaction proceeds through one‐pot, three‐component pathway, without the need for sensitive or harsh conditions. Organic photocatalysts were employed to generate aryl radicals more efficiently from diazonium salts generated situ. This method enables amines and methylthiolated alkynones, utilizing potassium metabisulfite as inexpensive source sulfur dioxide. resulting products obtained under mild approach provides efficient alternative pathway synthesizing thioflavone derivatives, which are prevalent among various bioactive compounds.
