We disclosed a TBHP mediated cyanoalkylation/cyanoalkenylation reaction of 2-anilino-1,4-naphthoquinones with vinylarenes/arylalkynes and azobis(alkylcarbonitrile)s in a one-pot three-component fashion via a radical cascade pathway.
An organophotocatalyzed synthesis of polycyclic quinazolinones with a distal nitrile group is reported in the aqueous medium.
Photoinduced direct electron transfer between azauracils and cycloketone oxime esters for C–H cyanoalkylation through a transiently assembled chromophore activation was developed.
Visible-light-driven EDA complex-promoted ring-opening of cycloketone oxime esters to synthesise various 4-cyanoalkylated isoquinoline-1,3-diones with acryloylbenzamides was developed.
Simple and practical strategies for visible-light-induced C–H alkylation of 2-amino-1,4-naphthoquinones with cyclobutanone oxime esters and hydroxamic acid derivatives have been developed under mild and redox-neutral conditions.
