摘要：

A variety of N-substituted pyrroles have been synthesized by reacting gamma-diketones with amines, diamines or triamine in the presence of silica sulfuric acid (SSA) at room temperature under solvent-free conditions. The experiment protocol features simple operations, and the products are isolated in high to excellent yields (70-98%). (c) 2010 Elsevier Ltd. All rights reserved.
