New and clean synthesis of N-substituted pyrroles under microwave irradiation
摘要:
N-Substituted homochiral pyrrole derivatives were synthesized by the ring-closure reaction of cis-1,4-dichloro-2-butene with various amine compounds on a silica surface under microwave irradiation. (c) 2007 Elsevier Ltd. All rights reserved.
We report an effective dynamic kineticresolution (DKR) system of racemic2-(1H-pyrrol-1-yl)alkanoic acids, which consists of a rapid racemization step via an activating substrate and an enantio-di...
