Abstract
The reaction of 2-hydroxy-2-phenacyl-1,3-indanedione with tosyl chloride in pyridine directly afforded in high yield the 11-benzoyl-1OH-indeno[2,1-b] indolizine-10-one the structure of which has been determined by single crystal X-ray diffraction. A possible pathway of this unexpected novel annulation reaction is discussed.Keywords
