The present invention has the following chemical formula which is disclosed in the specification; in the chemical formula, R1 and R2 are respectively one of Me, Et, i-Pr, n-Bu, c-C6 H11, (CH2)4, (CH2)5, CH (CH3)Ph, CH2 CH2 OCH2 CH2, and R1 and R2 can be identical and can also be different. The present invention uses spiro diphenol as raw material to react with substitution phosphoramidite so as to generate the spiro phosphoramidite. A spiro dihydroinden structure in the spiro phosphoramidite has axial chirality, so the compound has two optical isomers of dextral spiro phosphoramidite and sinistral spiro phosphoramidite; the spiro phosphoramidite can be used as chiral ligand for antisymmetrical catalytic hydrogenation reaction (dehydrogenation amino acid, enamine and itaconic acid), and has high stereo selectivity to the hydrogenation reaction; the e. e. value can reach more than 99%.
Description
Technical field
The invention belongs to the synthetic of chiral ligand compound, is a kind of C of having specifically
2The preparation of the Spirocyclophophorousamine amine of symmetry axis.
Background technology
A-amino acid is the important compound of a class, and they are playing the part of very important role in vivo with the polypeptide (protein) that the amido linkage bonding forms.By deep processing, can obtain the different compound of configuration, these compounds all have important purposes at biology in the pharmacy.It is synthetic that the a-amino acid of chirality can also be used for chirality as the chiral induction agent.Thereby the chirality of a-amino acid is synthetic to be the focus of organic synthesis always.The amino acid whose catalytic hydrogenation of dehydrogenation is the method that develops the earliest, is substrate with the dehydrogenation amino acid derivative, and hydrogenation takes place in the presence of chiral catalyst, obtains optically active amino acid product.In addition, also need to have in a large number the derivative of optically active carboxylic acid, alcohol and amine in synthetic fields such as medicine, agricultural chemicals, these can carry out hydrogenation and obtain by the reaction substrate that it is had latent chiral centre.
At present, the example of some industrialized catalytic hydrogenations has been arranged, for example BINAP, DIOP, DuPHOS etc.These compounds all are to have C
2The phosphorous bitooth ligand of symmetry axis.Though what have in these parts has a higher selectivity, they all have a fatal weakness, and that is exactly a poor stability, must use in nitrogen atmosphere, and are extremely inconvenient.
Summary of the invention
The objective of the invention is to disclose a kind of Spirocyclophophorousamine amine, it is the unidentate ligand of spirane structure.When Spirocyclophophorousamine amine of the present invention is applied to the catalytic hydrogenation of dehydrogenation amino acid, enamine and methylene-succinic acid, not only have very high selectivity, and stability is also fine.
