摘要:
A catalytic enantioselective O-nitroso aldol reaction of alkenyl trichloroacetates with nitrosoarenes was achieved using the (R,R)-t-Bu-QuinoxP*center dot AgOAc complex as the chiral catalyst and Bu(2)Sn(OMe)(2) as the achiral cocatalyst in the presence of methanol. Optically active a-aminooxy ketones with up to 99% ee were regioselectively obtained in high yields from various alkenyl trichloroacetates of cyclic ketones.
