The reactions of arenesulphonyl azides with tetrahydropyrido[1,2-a]indoles and the X-ray crystallographic structure determination of a resultant novel zwitterion, 1,2,3,4-tetrahydro-10-methyl-4a-p-tolylsulphonylaminopyrido[1,2-a] indole

Abstract

The reactions of arenesulphonyl azides with tetrahydropyrido[1,2-a]indoles have been examined. Compounds formed by elimination and by ring enlargement are obtained, including a compound with a novel zwitterion structure. The structure of this compound has been determined by X-ray crystallography.
