‐Aminopyridinium Salt Accelerated by Surfactant in Water
A light-promoted metal-free protocol for the amination of imidazo[1,2-a]pyridines with N-aminopyridinium salt by the assistance of surfactants in water was reported, charactering mild and environmentally benign conditions, as well as great functional group tolerance. Micelles with negatively charged polar surface and hydrophobic core formed from sodium dodecyl sulfate serve as an ideal medium for visible-light

Ionicliquids (ILs) have been labeled as a promising green alternative to traditional materials; however, many ILs have been discovered to be toxic, especially hydrophobic ILs (HILs). HILs are limited in their structural diversity as most are composed of heteroaromatic cations with long alkyl chains and paired with [BF4], [PF6], or [NTf2] anions. This study aims to diversify HILs by synthesizing two
and S1/S3 binding pockets at the enzyme active site. Their synthesis takes advantage of a solvent-free and highly diastereoselective conjugate addition of amines to bicyclic vinylsulfones. Structural optimization based on a little-known conformational preference of aryl sulfones produced the most potent inhibitors of this new class. In vitro assays demonstrate that the title compounds are capable of
