Optically active 2′-diphenylphosphino-1,1′-binaphthyls (MOP's) having various functional groups, cyano, aminomethyl, methoxycarbonyl, carboxy, and hydroxymethyl, at the C2-position were prepared. A cyano group was introduced on the MOP skeleton by nickel-catalyzed cyanation of 2-diphenylphosphinyl-2′-trifluoromethanesulfonyloxy 1,1′-binaphthyl which is readily prepared from optically active binaphthol
制备在C 2位具有氰基,氨基甲基,甲氧基羰基,羧基和羟甲基的各种官能团的旋光的2'-二苯基膦基-1,1'-联萘基(MOP's)。通过由光活性联萘酚容易制备的2-二苯基膦基-2'-三氟甲磺酰氧基1,1'-联萘的镍催化氰化作用,将氰基引入到MOP骨架上。带有羧基的MOP衍生物的制备是通过钯催化的2,2'-双萘基联萘的单羰基化,然后将剩余的三氟甲磺酸酯基进行膦化。
