synthesis of N-aroyl-2-arylindoles by reactions of 2 mol of various N-(2-iodoaryl)arylamides with 1 mol of calcium carbide through one-step procedure is described. This protocol has the salient features of the use of an inexpensive, abundant and easy-to-handle solid calcium carbide instead of flammable and explosive gaseous acetylene as an original alkyne source. In addition, wide scope of substrates, satisfactory
描述了一种通过 2 mol 各种N- (2-碘芳基)芳酰胺与 1 mol 电石一步反应合成N-芳酰基-2-芳基吲哚的有效方法。该方案的显着特点是使用廉价、丰富且易于处理的固体碳化钙代替易燃易爆的气态乙炔作为原始炔烃源。此外,底物范围广、产率令人满意、后处理程序简单也是该方法的优点。
