We describe a novel 1,2,2-trifunctionalization of maleimides with 1,7-enynes and oxime esters through simultaneous construction of four C−C bonds and a C≡N bond in one pot based on the radical relay/1,5-hydrogen-atom transfer (HAT).
The first N-heterocyclic carbene organocatalytic three-component radical relay trifunctionalization of unactivated alkenes through the combination of remote 1,4-cyano migration and alkylacylation was reported.
This feature article summarizes our achievements in radical-mediated intramolecular functional group migration reactions, aiming to provide a comprehensive understanding of the progress in this emerging area.
C bonds in vinyl azides to access densely functionalized phenanthridines enabled by the NCS/AgNO2 system
The NCS/AgNO2 system enables an unprecedented trifunctionalization of C
C bonds in vinyl azides to access densely functionalized phenanthridines in a one-pot manner.
A BPO triggered 1,2,3-trifunctionalization of α,α-disubstituted vinyl aldehydes enabled by radical 1,2-formyl migration is developed, providing a number of trifluoromethylated alkynyl aldehydes under mild conditions.
