substituted alkylpyrroles were synthesized in regioselective manner by the cyclization of nitroalkenes with imines catalyzed by Sm(Oi-Pr)3 under mild conditions. Tetrahydroindole derivative was also synthesized in fair yield by the use of cyclic nitroalkene and imine as starting material. This method provides a novel alternative route for the regioselective synthesis of substituted alkylpyrrole derivatives
在温和条件下,通过Sm(O i -Pr)3催化亚胺与亚硝基环合,以区域选择性的方式合成了各种类型的取代烷基吡咯。还使用环状硝基烯烃和亚胺作为起始原料以适当的产率合成了四氢吲哚衍生物。该方法为取代的烷基吡咯衍生物的区域选择性合成提供了新的替代途径。

2-Iodobenzoyl chloride reacts with aldimines in acetonitrile at 100° under carbon monoxide in the presence of a catalytic amount of bis(triphenylphosphine)palladium(II) chloride together with triethylamine to give the corresponding 3-alkenylisoindolin-1-ones in good yields.
