The AlCL3Catalyzed Benzoylation of Ethyl Pyrrole-2-Acetate: An Unusual 6-Substitution
摘要:
In this study, synthetic methodologies have been developed which are potentially useful in preparing 4- and 5-aroylpyrrole-2-acetic acids bearing no alkyl substituents on the heterocyclic nitrogen. These compounds are structurally related to a class of NSAIDs.

The pyrano[4,3-b]pyrrol-6-ones 7-9, 12 and 13 are stable cyclic analogues of pyrole-2,3-quinodimethane, and undergo Diels-Alder reaction with a range of alkynes to give, after loss of carbon dioxide, indoles.

An efficient Et3B-mediated oxidative radical substitution of substituted pyrroles and indoles using xanthate based radical chemistry in the presence of iron(II) sulfate is described. Unsubstituted indole gave only low yield or failed in the process. 2-Cyano-furan and 2-benzoylthiophene did not afford the corresponding alkylated products under these conditions.
