Key Points

  • This research aims to illustrate the use of triethylamine as an effective ethylene surrogate in ruthenium-catalyzed cycloaddition reactions.
  • Utilized a dinuclear ruthenium complex [Ru(p-cymene)Cl2]2 as a catalyst.
  • Conducted reactions under mild conditions with chromanone diene derivatives.
  • Employed triethylamine as an ethylene equivalent.
  • Successfully expanded ruthenium-catalyzed cycloaddition strategies for complex molecular architectures.
  • Demonstrated the practical utility of TEA in the cycloaddition process.

Abstract

A ruthenium-catalyzed 4 + 2 cycloaddition of chromanone diene derivatives using triethylamine (TEA) is described. TEA was employed as an ethylene equivalent, and a bench-stable dinuclear ruthenium complex Ru(p-cymene)Cl22 catalyzed the reaction under mild conditions. This study highlights the utility of TEA as a practical ethylene surrogate and expands the repertoire of ruthenium-catalyzed cycloaddition strategies for the efficient construction of complex molecular architectures.
