One-Pot Four-Component Synthesis of N2-Alkyl-N3-[2-(1,3,4-oxadiazol-2-yl)aryl]benzofuran-2,3-diamines
摘要:
AbstractA simple synthesis of N2‐alkyl‐N3‐[2‐(1,3,4‐oxadiazol‐2‐yl)aryl]benzofuran‐2,3‐diamines 5via 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).
