Recent developments in carbon 13 nmr and proton nmr


, : Recent developments in carbon 13 nmr and proton nmr. Journal of Natural Products (Lloydia) 47(2): 226-259

The fundamentals of pulsed Fourier transform NMR and nuclear spin dynamics are reviewed as a basis for explaining several recently developed experiments: APT (Attached Proton Test), INEPT [Intensive Nuclei Enhanced by Polarization Transfer], carbon-carbon connectivity, and a number of 2-dimensional versions of these basic pulse sequences. The general procedures for applying these experiments are outlined and examples of the results are given. The direct evidence of chemical bonding provided by these methods offers a more reliable procedure for structural determinations than traditional inferential methods based on spectral interpretation. Application of these techniques to natural product structure elucidation is illustrated by several examples [Hepialus californicus pheromone, insect growth inhibitor from marine algae, 5.alpha.-androstane.].
