Abstract

A simple and efficient one-pot procedure for the synthesis of new pyrrolo[2,3-d]pyrimidine derivatives has been established through an l-proline-catalyzed cyclization of 6-aminopyrimidine-4(3H)-one with nitroolefins in water. The reaction at 80 °C in water gives various highly substituted pyrrolo[2,3-d]pyrimidines in good to excellent yields. This procedure has the advantages of environmental friendliness, good yields, and convenient operation.
