The dimeric products (1a-c) have ben prepared by treatment of N-oxides derived from some indole alkaloids.Their structures have been elucidated by detailed NMR investigations and the structure of 1c determined by X-ray analysis.The importance of the E2-type trans-axial elimination of the N-acyloxy intermediate in the dimer formation has also been established.The iminium salts 4a-b and the derived pseudocyanide 6 have been prepared.
