Containing a biphenyl skeleton of a chiral compound and its preparation method and application (by machine translation)
The invention relates to a containing a biphenyl skeleton chiral compounds and its preparation method and application, chiral compound of the chemical formula is Wherein R1 , R2 Are each independently selected from hydrogen, methyl, tert-butyl, halogen, phenyl, substituted phenyl, naphthyl or substituted naphthyl, R3 Selected from vinyl, carboxyl or diphenylphosphine, R4 Selected from sulfur, oxygen or selenium, R5 Sulfuryl amidogen selected from hydroxyl or trifluoromethanesulfonate, R6 Selected from sulfur or oxygen; by chiral compound (R)- 3, 3 ‘- di-tert-butyl – 5, 5’ – dibromo – 6, 6 ‘- dimethyl – 1, 1′ – biphenyl – 2, 2’ – prepared by diphenol; chiral compounds as a catalyst, for catalytic asymmetric reactions. Compared with the prior art, the present invention provides a series of based on the biphenyl skeleton of chiral compounds, including chiral phosphoric acid, diphosphine, phosphorus amide, thiophosphoric acid, phosphoroamido, diene, dicarboxylic acid and the like, these chiral compounds can be used in the asymmetric reaction in the catalyst, and the structure is relatively simple, easy to synthesize preparation, application prospect.
