The equilibrium structures of nine C2 sparteine derivatives have been investigated with the density functional theory, using the B3LYP method. The substituents at C2 position have been a methyl-, phenyl-, p-tolyl- or a cyano group. For all derivatives investigated the dominant conformer is that with the boat–chair system of the C/D rings. The NMR chemical shifts, calculated by the continuous set of...
