Product Application： (11bS)-N,N-dimethyl-8,9,10,11,12,13,14,15-octahydrodinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-amine is a monodentate phosphoramidite (MonoPhos) chiral ligand that can be used: In the Cu-catalyzed synthesis of chiral 3-(arylbut-1-yn-1-yl)silane derivatives by reacting N-tosylhydrazones with silyl-substituted alkynes via asymmetric insertion. In the Rh-catalyzed asymmetric hydrogenation of R-isopropylcinnamic acid derivative, a key intermediate of renin inhibitor aliskiren. In the Rh-catalyzed conjugate addition of arylboronic acids to lactones, enones, and nitroalkenes.
