Chiral sulfide – phosphine ligand and preparation method and use thereof (by machine translation)
The present invention provides novel chiral sulfide – phosphine ligand and its preparation and use, the ligand shown in formula I compound or its enantiomer, non-enantiomer, racemate, pharmaceutically acceptable salt, crystalline hydrate or solvate. Wherein R1 Is an optionally substituted phenyl, optionally substituted naphthyl; R2 Is methyl, benzyl; the present invention provides chiral sulfide – phosphine ligand as copper catalytic asymmetric cycloaddition reaction of the ligand, can be directly used for preparing the various having multi-substituted chiral central tetrahydro pyrrole compound.
