Technical Notes：

1. Ligand used for Rh-catalyzed asymmetric hydroformylation reactions of styrene, allyl cyanide, and vinyl

acetate.

2.Ligand for Ir catalyzed asymmetric transfer hydrogenation of ketones.

3.Ligand for Cu-catalyzed enantioselective hydroboration of a- and ß-unsaturated esters and nitriles .

4.Used for Au-catalyzed chemoselectiv cycloisomerization of furyldialkyne to the rac-tetrahydronaphthalenediol.

5.Used in enantioselective Pd-catalyzed conjunctive cross-coupling of bis(alkenyl)borates to generate chiralallylborons.

6.Ligand used in Pd-catalyzed a three -component aminoarylation of alkynes to generate enamines with subsequent hydrolysis to either a-arylphenones or a,a-diarylketones.
