Notizen:
The 1H and 13C NMR spectra of the parent tetramethyl 9aH-quinolizine-1,2,3,4-tetracarboxylate and 20 of its alkyl-substituted derivatives were obtained and analysed. The study included measurements of one-bond carbon-carbon and also proton-proton coupling constants across three, four, five and six bonds. An analysis of the data allowed an estimation of electron distribution and steric requirements in this group of compounds. No correlation was observed between 1J(C,C) values and the corresponding bond lengths.
