Fund Project: We thank The Ministry of Education of The People's Republic of China, Department of education of Jiangxi Province and Jiangxi Provincial Natural Science Foundation for financial support. We also appreciate The Analysis Center of Nanchang University for physical characterization of all the compounds. Special thanks to Dr. Yu Jin-Quan in Scripps Institute in the United States of America for his highly valuable assistance.

The reaction of 2-formylpyrrole acetals with sodium alkoxide in alcohols at reflux temperature smoothly proceeded to generate corresponding transacetalization products in nearly quantitative yields. A plausible mechanism involving the formation of a highly reactive intermediate azafulvene species was proposed to explain the observed transformation.
