1,2,3-Triazol-5-ylidenes have recently attracted considerable attention as versatile ligands because of their strong electron-donating properties and structural diversities. While some efforts have been devoted to the development of chiral triazolylidene-

The present invention provides a chiral P based on the skeleton of the phenethylamine, N, N ligand compound and its manufacturing method and application, surfactant-ethylamine skeleton chiral P, N, N ligand compound of preparation method is as follows: under the protection of nitrogen, the chiral phenylethylamine - [...] compound with 2 - chloromethyl oxazole oxazoline compounds soluble in the reaction solvent, adding alkali, reflux reaction, filtering, desolvation, column chromatography to obtain the required chiral P, N, N ligand compound. In particular to the β - ketoacid ester compound in asymmetric catalytic hydrogenation reaction. The invention of the phenethylamine skeleton chiral P, N, β - keto ester N ligand can be applied to the asymmetric catalytic hydrogenation reaction, can be high yield and high enantio-selectively for the preparation of chiral β - hydroxy ester.

The potential of using chiral bicyclic NHC ligands that exhibit modularity was investigated in the Cu-catalyzed asymmetric borylation reaction of α,β-unsaturated esters. After screening for ligands and optimization of the reaction conditions, the corresponding products were afforded with good enantioselectivities (up to 85% ee).
