General Description

N-Cyclohexylmaleimide (CHMI, NCMI) is a cyclic imide. Diels-Alder reactions of 9-hydroxymethylanthracene with CHMI catalyzed by hydrophobic nanospace confined within the self-assembled Pd6 open cage bearing triimidazole walls have been reported. It undergoes Diels-Alder reactions with various aromatic hydrocarbons promoted by self-assembled coordination cage. This cage acts as nanometer-sized molecular flask and hence promotes this reaction. CHMI is reported to undergo radical polymerization readily under various polymerization conditions to afford poly(CHMI), having excellent thermal stability.

Dual organic dyes as a pseudo-redox mediation system to promotion of tandem oxidation /[3+2] cycloaddition reactions under visible light

An atom- and step-economy protocol has been developed to synthesize some new biologically active pyrrolo[2,1-a]isoquinoline alkaloids via redox mediation system under visible light irradiation. A vast variety of double and triple bonds, as dipolarophiles, treated with in situ generated azomethine ylides to prepare corresponding products in good to excellent yields. This metal-free method effectively promoted oxidation/[3 + 2] cycloaddition/oxidative/aromatization domino reaction without further oxidant using dual organic dyes as pseudo-redox mediation system. Besides, for most of the products, product precipitate was readily separated from reaction media. To the best of our knowledge, this is the first report of dual dyes as a pseudo-redox mediation system.

Regioselective hydroarylation and arylation of maleimides with indazoles: Via a Rh(iii)-catalyzed C-H activation

Switchable Rh(iii)-catalyzed highly regioselective hydroarylation and oxidative arylation of maleimides with 2-arylindazoles via C-H activation have been demonstrated. The reaction affords 3-(2-(2H-indazol-2-yl)phenyl)succinimide and 3-(2-(2H-indazol-2-yl)phenyl)maleimide derivatives in high yields with wide functional group tolerance. A mechanistic study was performed to depict C-H bond cleavage that might be involved in the turnover limiting step.
