Abstract
Base-catalyzed domino cyclization of allenes with 3-chloro-2-formylindoles in PEG-400 was investigated. Pyrroloindoles were formed stereoselectively as single products. The structure of the product depends on the type of allene used. Two compounds have been characterized by single crystal X-ray diffraction. © Georg Thieme Verlag Stuttgart · New York.
