An efficient solvent-dependent regioselective [3 + 2]-cycloaddition/iodocyclization cascade reaction of alkyne-tethered chalcones/cinnamates and TosMIC has been developed. The reaction represents a novel protocol for the expedient and divergent one-pot synthesis of benz[e]indoles and spiro[indene-1,3′-pyrroles] from acyclic common precursors at room temperature.
已经开发了一种有效的溶剂依赖的炔烃系查耳酮/肉桂酸酯和TosMIC的区域选择性[3 + 2]-环加成/碘环化级联反应。该反应代表了在室温下由非环状常见前体方便,多样地合成苯并[ e ]吲哚和螺[indene-1,3'-吡咯]的新颖方法。
