As such, it presents a set of brand new tools, including vinylogous Mukaiyama-aldol reactions, substrate-controlled aldol reactions and asymmetric induction in aldol additions. Natural product classes covered include carbohydrates, amino acids, redox economies, practical aspects and environmental awareness. Woodward weighed in four years later with a slightly shorter formal synthesis that relied on very similar tactics, but would probably be much harder to make asymmetric. Samarium(II)-Iodide-Mediated Cyclizations in Natural Product Synthesis. Biomimetic Synthesis of Polycyclic Natural Products from Acyclic Precursors. Comprehensive Enantioselective Organocatalysis: Catalysts, Reactions, and Applications, 3 Volume Set. Theory of Asymmetric Organocatalysis of Aldol and Related Reactions: Rationalizations and Predictions. Throughout, all of these methodologies are presented in the context of their deployment in total synthesis of natural products. Allemann, C.; Gordillo, R.; Clemente, F. This is followed by chapters on each of the major individual classes of natural products; their structures, biosynthesis and interrelationships as well as examples of asymmetric syntheses and the practical value of these compounds. I've heard it said a few times that if you can't be the first to synthesise a natural product, then you should try and be the last; that is, you should aim to come up with the most elegant and efficient route you can now that the pressure's off and there's less of a rush. Furthermore, novel developments aldol additions. Toste also David MacMillan at Princeton dramatically expanded the power of organocatalysis with his SOMO (singly occupied molecular orbital) strategy (CW May p24). Berkeley's Dean Toste showcased the metal's catalytic utility throughout the year, using gold to turn simple alkene precursors into complex cyclic molecules[1], including fawcettimine - the first asymmetric synthesis of this natural product coming almost 50 years after its discovery[2]. Organocatalysis has emerged completely in the last ten years, and has been fully integrated into this new edition .
