Abstract

Abstract : In this article, we describe the characteristic 15 N and 1 HN NMR chemical shifts and 1 J ( 15 N– 1 H) coupling constants of various symmetrically and unsymmetrically substituted 1, 4‐dihydropyridine derivatives. The NMR chemical shifts and coupling constants are discussed in terms of their relationship to structural features such as character and position of the substituent in heterocycle, N ‐alkyl substitution, nitrogen lone pair delocalization within the conjugated system, and steric effects.
