An operationally simple, practical, and economical protocol for iron(III) chloride catalyzed Paal-Knorr pyrrole synthesis in water in good to excellent yields has been developed. Several N-substituted pyrroles are readily prepared from the reaction of 2,5-dimethoxytetrahydrofuran and aryl/alkyl, sulfonyl and acyl amines under very mild reaction conditions
一种操作简便、实用且经济的实验方案已被开发,用于在水相中以铁(III)氯化物为催化剂进行Paal-Knorr吡咯合成,产率良好至优异。在非常温和的反应条件下,多个N-取代吡咯可以方便地通过2,5-二甲氧基四氢呋喃与芳基/烷基、磺酰基和酰基胺的反应来制备。
