Abstract

A method for synthesis of substituted pyrroles has been developed. 1-Sulfonyl-1, 2, 3- triazoles generated from terminal alkynes gave α-imino rhodium carbene complexes, which when reacted with alkenyl alkyl ethers afforded substituted pyrroles. The method can be efficiently applied to a one-pot sequential reaction starting from terminal alkynes.
