A convenient method for oxidant-promoted radical cascade acylation or decarbonylative alkylation of 1,7-dienes with aldehydes for the construction of tetracyclic N-containing skeletons has been established.
Electron-withdrawing ligands increase epoxidation activity, but decrease oxyanion reduction catalysis.
A straightforward transition-metal-free sustainable methodology for oxidative cyclopropanation of aza-1,6-enynes has been devised, enabling the synthesis of valuable, functionalized azabicyclo[4.1.0]heptane-2,4,5-triones.
A paired electrolysis enabled amination of arenes using N,N-dialkyl formamides as the amine source for the synthesis of arylamines without the need for chemical oxidants, metal catalysts or high temperatures is reported.
One novel straight approach to acylated quinoxalin-2(1H)-one N-oxides was achieved with arylaldehydes using the Cu(I)/TBHP system. The dual functional cross-coupling reaction underwent a free radical relay process.
