The preparation of 1-(3-indolylethyl)-2-cyanotetrahydropyridines (3a) and (3b), bearing a protected acetaldehyde chain at the indole 2-position, is reported. Acid treatment of (3a) and (3b) leads to products resulting from disproportionation of the initially formed dihydropyridinium cation.

Abstract
The preparation of 1-(3-indolylethyl)-2-cyanotetrahydropyridines (3a) and (3b), bearing a protected acetaldehyde chain at the indole 2-position, is reported. Acid treatment of (3a) and (3b) leads to products resulting from disproportionation of the initially formed dihydropyridinium cation.
