A novel application of (PhO) 3 P-Cl 2 chemistry to the synthesis of 2-substituted and 2,3-disubstituted pyrroles from N-allylamides is illustrated. A mild procedure is used to generate the imino chloride intermediates, which are subsequently cyclized to pyrroles. The products are smoothly obtained in moderate to good overall yields.
说明了 (PhO) 3 P-Cl 2 化学在从 N-烯丙基酰胺合成 2-取代和 2,3-二取代吡咯的新应用。使用温和的程序生成亚氨基氯化物中间体,随后将其环化为吡咯。产品以中等至良好的总产率顺利获得。
