Picolylamine Template Organocatalysts for Asymmetric Aldol reactions: Pyridine based Organocatalysts for Asymmetric Aldol Reacti,Used
Delivery time: 8-12 business days (International)
The synthesis of enantiomerically pure compounds is one of the major areas of organic chemistry, with emphasis on the elaboration of commodity chemicals into high value enantiopure advanced building blocks. Asymmetric organocatalysis, where chiral organic molecules catalyze enantioselective reactions, has grown explosively and become a main focus of research. In the past 5 years different chiral primary amine derived organocatalysts, usually based on naturally occurring cinchonine alkaloids, have been shown for asymmetric Aldol, Michael, Mannich and aamination reactions. The results have been impressive but many substrates remain untested or are still challenging, and will be required to overcome the limitations of the nonmodular, fixed, cinchonia template. To try and overcome these problems, we have designed and synthesized pyridineprimary amine bifunctional catalysts with a similar juxtaposition of vital functionality as cinchonia alkaloids. The important design feature is the modular nature of the new organocatalysts in combination with the brevity of their synthesis. Our chiral pyridineprimary amine catalysts are likely candidates for Aldol reactions.
By changing our most important processes and
products, we have already made a big leap forward. This ranges from the
increased use of more sustainable fibers to the use of more
environmentally friendly printing processes to the development of
efficient waste management in our value chain.
