N-Heterocyclic Carbene-Catalyzed Intramolecular Aldehyde−Nitrile Cross Coupling: An Easy Access to 3- Aminochromones
摘要:
An immense effort has been made to develop an efficient strategy for the carbon-carbon bond formation between aldehyde and nitrile intramolecularly using an N-heterocyclic carbene catalyst to derive 3-aminochromone derivatives in good to excellent yields (80-95%).
