2,3‐Disubstituted benzo[b]furans are prepared in one step from commercially available phenols and readily accessible unactivatedinternalalkynes (see scheme). This Pd‐catalyzed oxidativeannulation has a broad substrate scope and allows access to a wide range of benzo[b]furans.
2,3-二取代的苯并[ b ]呋喃一步一步由市售的苯酚和易于获得的未活化内部炔烃制得(参见方案)。这种Pd催化的氧化环化具有广泛的底物范围,并允许使用各种苯并[ b ]呋喃。

Condensation of 5-formyl-6-methoxy-2,3-diphenylbenzofuran (I) and 6-formyl-5-methoxy-2,3-diphenylbenzofuran (II) with aliphatic or aromatic primary amines led to the formation of the corresponding anils (IIIa-k and IVa-c). The anils (IIIa,f,k or IVa-c) reacted with ethyl cyanoacetate, ethyl acetoacetate, or diethyl malonate to form the respective esters (Va-c or VIa-c). When Va-c or VIa-c were treated
