NMR Techniques for the Structure Elucidation and Conformational Analysis of Natural Products,in the literature could be regarded as proven unambiguously. Rather, reliance is usually placed either on model compounds or on additive or subtractive shifts based on the data for simple analogues. As a result, numerous proton and carbon-13 assignments must be either reconfirmed or revised, even in well-established natural products.

Novel Carbohydrate Transformations Discovered en Route to Natural Products, the limits of current synthetic methodology. In the course of these adventures, unexpected reactions are almost certain to occur, and although these are initially unwanted, it is from such reactions that new science arises. The very fact that they were “unexpected” means that the potential exists f

in these advan ces has been the advent of powerful superconducting magnets with very stable magnetic fields, and pulse NMR in which the duration, direction and phases of pulses can be accurately controlled by means of mini computers. These have heralded the advent of two-dimensional NMR spec troscopy which978-3-642-74019-0978-3-642-74017-6
