New imidazolium/pyrrolidinium-tagged Indabox ligands were designed and prepared. Catalysts based on these ligands with Cu(OAc) 2 ·H 2 O were applied to the asymmetric Henry reaction using various aldehydes and CH 3 NO 2 , the products were obtained in high enantioselectivity. Specifically, (R)-1-(2-methoxylphenyl)-2-nitroethanol was obtained in 94% ee in MeOH. Furthermore,...
