A new method is proposed for the production of derivatives of thieno[2,3-b]pyrrole on the basis of acid-catalyzed recyclization of the furan ring in 2-R-amino-3-furfurylthiophenes. It was established that the direction of the transformations occurring under the influence of a mixture of hydrochloric and acetic acids and also the structure of the obtained compounds depend on the nature of the protecting group.
