A three-component reaction of cyclobutanone oxime esters, DABCO·(SO2)2 and N-alkyl-N-methacryloyl benzamides was developed for the generation of sulfonyl-containing isoquinoline-1,3-(2H,4H)-diones.
In this review, we conclude recent main themes in trapping SO2, CO or O2 by cyanoalkyl radicals, which are produced from iminyl-radical-triggered C–C bond cleavage of cyclobutanone oxime derivatives.
Cyanoalkylsulfonylation of Morita–Baylis–Hillman (MBH) acetates with cycloketone oxime esters using sodium dithionite (Na2S2O4) as both a single electron reductant and SO2 source has been demonstrated.
This review highlights the advances from the past decade that provide readers with essential tools for designing and implementing radical sulfonylation using SO2 surrogates in organic synthesis.
A ferrocene catalyzed difunctionalization of aryl alkenes using cycloketone oxime esters as bifunctional reagents is reported.
