Description
Technical Field
The invention particularly relates to a chiral diphosphine skeleton compound, a preparation method and application thereof.
Background
Chiral ligands play an extremely important role in asymmetric catalytic synthesis of metal participation. Thus, efforts have been made for the last forty years to develop chiral ligands with high activity and selectivity. So far, chiral ligands with the so-called "dominant structure" (specific references s.—f.zhu, q.— L.Zhou, inPrivilegedChiralLigandsandCatalysts, ed.: q.—l.zhou, wiley-VCH, weinheim,2011, pp.137-170) are widely used. Representative ligand backbones are BINOL, BINAP, bisoxazoline, salen, duPhos, TADDOL, cinchonaalloid, et al. Based on these "dominant structure" ligand backbones, a number of chiral ligands can be extended. Experimental results indicate that most of the ligands can exhibit excellent enantioselectivity in many metal-catalyzed asymmetric catalytic reactions. However, with the progress of the whole asymmetric catalytic reaction and chiral drug development, scientists have found that there are a large number of asymmetric reactions lacking efficient chiral ligands. Therefore, further development of chiral ligands with novel backbones, particularly development of chiral ligands that are inexpensive, easy to obtain and efficient, remains one of the very important and challenging problems. Based on the above characteristics, we intend to develop a novel class of chiral diphosphine ligands.
