Stereochemistry of Cyanide Ion Addition to 3,4,5,6-Tetrahydropyridinium Derivatives

Essawi, M. Y. H.,Portoghese, P. S.

, p. 2138 - 2140 (2007/10/02)

The stereochemistry of cyanide ion addition to 1-alkyl-4-(N-phenylpropanamido)-3,4,5,6-tetrahydropyridinium salts 2 was investigated by analysis of the 1H NMR spectra of the isolated α-amino nitriles.The data obtained, together with epimerization studies, indicated that the addition occurred in a stereospecific manner to afford the trans diastereoisomeres.
