An efficient one-pot reaction between isocyanides, anilines, and salicylaldehydes (2-hydroxybenzaldehydes) in the presence of a Lewis acid proceeds smoothly at room temperature within a short time interval to afford aminobenzofurans and N-alkyl-2-aryl-2-(arylimino)acetamide derivatives in high yields depending on the electron density of the aniline component.
