Description

General description

4-Nitrobenzenesulfonamide is the nitrene source during on pot procedure for copper(I)-catalyzed asymmetric alkene aziridination. It reacts with diazacrown ether, N,N′-dibenzyl-1,7,10,16-tetraoxo-4,13-diazacyclooctadecane to form molecular complexes.

Nitroreductases (NRs) and ene-reductases (ERs) both utilize flavin mononucleotide cofactors but catalyze distinct reactions. NRs reduce nitroaromatics, whereas ERs reduce unsaturated C=C double bonds, and these functionalities are known to somewhat overlap. Recent studies on the ER xenobiotic reductase A
