Published: October 2012

The three-component formal [3 + 3] aza-annulation between chalcones, β-ketoamides, and ammonium acetate in the presence of CAN as a Lewis acid affords good to excellent yields of highly substituted nicotinamides or their fused derivatives. This transformation leads to the formation of one C-C and two C-N bonds in a single synthetic operation and involves up to five individual steps.

We show that 2-diynylpyridine and a Bpin-terminated monoyne or diyne will cross-react to form benzyne intermediates. These reactive intermediates are captured by various in situ trapping agents to give products of three-component reactions. Various control reactions, substrate modification, binding studies, and DFT analysis suggest that a small amount of a noncovalent Lewis acid-base complex is the active species within which the diyne and diynophile engage to produce the benzyne.

Article Synopsis
  • Radical-mediated cross-coupling reactions are a powerful method for creating diverse molecular structures, but they face challenges in controlling reaction pathways and selectivity due to the high reactivity of radicals.
  • The use of visible-light photoredox catalysis combined with chiral copper catalysts can enhance control over radical species and improve enantioselective reactions.
  • This research focuses on innovative strategies for chiral C-C and C-O bond formation by utilizing dual photoredox/copper catalysis, highlighting the effectiveness of visible light in achieving selectivity in these reactions.

An expedient route to 2-aminodihydrothiophenes and their seleno analogues is reported. A three-component photoredox reaction between alkene, thio(seleno)cyanate, and bromomalonate is employed, generating a carbo-thio(seleno)cyanate intermediate that undergoes a domino of reactions mediated by alumina column chromatography, leading to valuable chalcogen pharmacophores. Mechanistic investigations using DFT and control experiments reveals an intramolecular H-bond responsible for driving the domino forward.

In this paper, an alternative and efficient copper(I)-catalyzed synthesis of 2-sulfonyliminocoumarins is developed through a three-component reaction of -hydroxybenzyl alcohol, alkynes, and -toluenesulfonyl azide. The proposed route for access to the 2-iminocoumarin ring involves a [4 + 2] hetero-Diels-Alder reaction between -quinone methide and ketenimine intermediates generated in situ.
