  • Title: Gold-catalyzed cyclization of alkynylaziridines as an efficient approach toward functionalized N-phth pyrroles.
    Author: Du X, Xie X, Liu Y.
    Journal: J Org Chem; 2010 Jan 15; 75(2):510-3. PubMed ID: 20000736.
    Abstract:
    An efficient access to N-phth pyrrroles via gold-catalyzed cycloisomerization of N-phth alkynylaziridines has been described. Functionalized pyrroles including pyrrole-2-carboxylates or 2-pyrrolyl ketone are easily constructed in generally good yields by this method. The resulting pyrroles can be further converted to N-amino pyrrole or 2-acyl pyrrole, which are important synthetic intermediates for amplification of molecular complexity.
