A Novel Four-Component Reaction between Secondary Amines and Hydroxybenzaldehydes with Isocyanides in Water: An Efficient One-Pot and Green Synthesis of Benzo[b]furan Derivatives
The novel benzo[b]furan derivatives, 7a–i, were synthesized and characterized by Ugi four-component reaction between 2-hydroxybenzaldehyde derivative 1, a secondary amine 2, and an isocyanide 3 in water. Those reactions were carried out at room temperature with moderate to good yields in one pot.
