A series of 2- and 3-indolylpyrroles were generated via 1,3-dipolar cycloadditions between (2-nitrovinyl)indoles and symmetrical and unsymmetrical 1,3-oxazolium-5-olates (munchnones).

A variety of 2-, 3-, and 4-pyridylpyrroles were synthesized in good to excellent yields via the 1,3-dipolar cycloaddition of symmetrical and unsymmetrical munchnones and nitroalkenes. The unsymmetrical munchnones show moderate to excellent regioselectivity. (C) 2011 Elsevier Ltd. All rights reserved.
