Methods for the preparation of thieno[2,3-b]-, -[3,2-b]-, -[3,4-b]-, -[2,3-c]-, and -[3,4-c]pyrroles are reviewed. The methods are classified according to the ring to be constructed: syntheses from thiophenes or syntheses from pyrroles, and according to starting materials. Finally, Tables of most of the compounds known are given. 1. Introduction 2. Syntheses from Thiophene Derivatives 3. Syntheses from Pyrrole Derivatives 4. Miscellaneous Syntheses 5.
