New chiral salen chemical compound, being the chiral salen chemical compound which is displayed with the mannered null chemical formula 1 which produces kiraru chemical compound from chiral salen

摘要

And to provide a method for producing chiral compounds from the racemate mix epoxide using this Kirarusaren and new catalysts. More specifically, it has a new molecular composition, and be reused without going through the catalyst regeneration process additional even after use in the reaction, in order to maintain catalytic activity for the same, and re-iteratively without catalyst regeneration process and Kirarusaren novel catalysts with advantages used not only possible, that very little racemization of the desired chiral compound that is also generated after completion of the reaction, or not occur, and use Kirarusaren catalysts such novel And then there is provided a process for producing an economical mass production of chiral compounds of high optical purity which can be used to produce raw materials for food additives or pharmaceuticals chiral possible.
