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.

Discovery and Chemistry of Naturally-Occurring Anticancer Agents, U.S. National Cancer Institute is reviewed..Structural work and chemistry is reported for active compounds from ., .s, ., ., . species, ., and .. A number of these novel compounds exhibit sufficient activity to initiate studies of their mechanism of action and analog synthesis.

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
