Description
Technical Field
The invention belongs to the technical field of organic chemical synthesis, and particularly relates to a synthesis method of chiral 5,5', 6' -tetramethyl-3, 3' -di-tert-butyl-1, 1' -biphenyl-2, 2' -diol catalysts.
Background
For the first synthesis of this type of framework, a patent was reported in 1999. Later synthetic reports on such backbones are also focused on patents. The first chemical synthesis of this type of scaffold was reported in 2006 (Chemistry-a European journal 2006, 12, 7482-7488), siegfried r. Waldvogel reported the synthesis of this type of scaffold using electrochemical anodic oxidation. Iwao Ojima in 2003 uses phosphites of this type of backbone as ligands (org. Lett. 2003, 5, 21, 3831-3834), catalyzing asymmetric hydrogenation reactions, which are the first reported monodentate phosphite ligands from enantiomerically pure axial chiral bisphenols. Subsequently, phosphite ligands of this type of framework are also utilized to catalyze a series of chiral reactions such as asymmetric hydroformylation of allyl cyanide. By 2007, first examples of the skeleton monodentate phosphoramide ligand are reported (Angew, chem, int, ed. 2007, 46, 1497-1500) and are applied to high enantioselective asymmetric hydrogenation reaction induced under iridium catalysis. By 2008, methyl and isopropyl substituted ligands of the framework phosphoramide are synthesized by respectively utilizing hexamethylphosphoric triamide and dichloro-N, N-diisopropyl phosphoramidite. In recent years, the synthesis of phosphoramide ligands with such frameworks is mainly focused on the expansion of substituents on different nitrogen. Until 2010 Anna g.wenzel (eur.j. Org. Chem. 2010, 3027-3031) reported that-NHTf substituted sulfides of this type of backbone were used as catalysts to catalyze the reaction, which is also the only example of sulfides of this type of backbone. While alkyl substituted selenium/sulfides for phosphoramides of this backbone are not reported. Therefore, based on previous reports, the use of such backbones as ligands is relatively broad, so that the alkyl substituted selenium/sulfide of phosphoramides of such backbones we have developed is very important and necessary.
