Methods of inhibiting the cytokine or biological activity of Macrophage Migration Inhibitory Factor (MIF) comprising contacting MIF with a compound of formula (I) are provided. The invention also relates to methods of treating diseases or conditions where MIF cytokine or biological activity is implicated comprising administration of compounds of formula (I), either alone or as a part of combination therapy. Novel compounds of formula (I) are also provided for.
We report that the nucleophilic acyl substitution reaction of aliphatic and (hetero)aromaticamides by organolithium reagents proceeds quickly (20 s reaction time), efficiently, and chemoselectively with a broad substrate scope in the environmentally responsible cyclopentyl methyl ether, at ambient temperature and under air, to provide ketones in up to 93 % yield with an effective suppression of the

The directdecarboxylativearylation of α‐oxo acids has been achieved by synergistic visible‐light‐mediated photoredox and nickelcatalysis. This method offers rapid entry to aryl and alkyl ketone architectures from simple α‐oxo acid precursors via an acyl radical intermediate. Significant substrate scope is observed with respect to both the oxo acid and arene coupling partners. This mild decarboxylative

Dehydrative Friedel–Craftsacylationreaction of aromatic compounds with carboxylic acids as acylating agents was investigated in the presence of Lewis acid- or Brønsted acid-catalyst. Various metal triflates and bis(trifluoromethanesulfonyl)amides showed catalytic activity at high temperature, among which Eu(NTf2)3 proved to be the most effective and efficiently catalyzed the acylationreaction of alkyl-
Rare-earth metal Lewis acids, in particular Eu(NTf2)3, were found to be efficient catalysts for Friedel–Craftsacylationreactionusing aliphatic as well as aromatic carboxylic acids as acylating agents at high temperature.
