dcterms:description
15N NMR parameters are sensitive indicators of the structural and electronic arrangements in organic and bioorganic compounds. The present contribution is a continuation of our previous study on the 15N NMR spectroscopy of isoquinoline alkaloids. The selected alkaloids belong to the protoberberine, benzophenanthridine, proaporphine, aporphine, pavinane, rhoeadine, cryptolepine, neocryptolepine and phtalideisoquinoline classes of alkaloids and were investigated by gradient-selected inverse-detected multiple bond correlation experiments (GHMBC and GSQMBC). The values of the 15N chemical shifts will be discussed in terms of the structural arrangements and the 1H-15N coupling pathways in relation to the geometrical parameters determined by X-ray structural analysis. Developing X-ray and 15N NMR data banks for various arrangements of alkaloids offer the opportunity of incorporating the additional restraints represented by the 15N chemical shifts and 1H-15N coupling pathways into the protocols of structural 15N NMR parameters are sensitive indicators of the structural and electronic arrangements in organic and bioorganic compounds.
