摘要：

A simple synthesis of N2-alkyl-N3-[2-(1,3,4-oxadiazol-2-yl)aryl]benzofuran-2,3-diamines 5 via a one-pot four-component reaction is described (Scheme 1). A mixture of N-(isocyanoimino)triphenylphosphorane (1), a 2-aminobenzoic acid 2, a 2-hydroxybenzaldehyde 3, and an isocyanide 4 in absolute EtOH at room temperature undergoes a smooth reaction to afford 5 in excellent yields (Table).
