    N-Heterocyclic carbene (NHC) catalyzed lactonization and lactamization of 2-bromoenals with heterocyclic C–H acids proceeding via the α,β-unsaturated acyl azolium intermediates is reported. The reaction furnished coumarin- or quinolinone-fused lactone/lactam derivatives. In addition, results of the enantioselective version of this reaction using chiral NHC are presented.

  • A highly efficient CuI nanoparticles-catalyzed synthesis of tetrahydrochromenediones and dihydropyrano[<i>c</i>]chromenediones under grinding

    Abstract

    A concise and CuI nanoparticle-catalyzed synthesis of tetrahydrochromenediones and dihydropyrano[c]chromenediones under solvent-free grinding conditions via the three-component condensation reaction of Meldrum’s acid, an aromatic aldehyde, and an active methylene compound, including dimedone or 4-hydroxycoumarin, was developed. This new method gives desirable advantages such as simple reaction setup, very mild reaction conditions, production of the desired products in high yields without by-products, recyclability of the catalyst, and environmentally benign procedure.

    Reactions of cyclic 1,3-dicarbonyl compounds with 1-(2-alkenoyl)-4-bromo-3,5-dimethylpyrazoles under the double catalytic activation conditions using both catalytic amounts of Lewis acid and amine catalysts provide a new direct synthetic route to enol lactones. Thus, 1,3-cyclohexanedione is allowed to react with 4-bromo-1-crotonoyl-3,5-dimethylpyrazole, in tetrahydrofuran at room temperature in the
