super(15)N NMR of 1,4-dihydropyridine derivatives

In this article, we describe the characteristic super(15)N and super(1)H sub(N) NMR chemical shifts and super(1)J( super(15)N- super(1)H) coupling constants of various symmetrically and unsymmetrically substituted 1,4-dihydropyridine derivatives. The NMR chemical shifts and coupling constants are di...

Description
Summary:In this article, we describe the characteristic super(15)N and super(1)H sub(N) NMR chemical shifts and super(1)J( super(15)N- super(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.
