  • Title: Efficient synthesis of highly substituted Pyrrolin-4-ones via PIFA-mediated cyclization reactions of enaminones.
    Author: Huang J, Liang Y, Pan W, Yang Y, Dong D.
    Journal: Org Lett; 2007 Dec 20; 9(26):5345-8. PubMed ID: 18047359.
    Abstract:
    A convenient and efficient synthesis of highly substituted pyrrolin-4-ones is developed via the PIFA-mediated cyclization reactions of readily available enaminones, and a mechanism involving sequential cleavage of N-C bond, formation of new N-C bond, intramolecular addition reaction, and benzilic acid type rearrangement is proposed.
