Asymmetric cyanation of trimethylsilyl cyanide (TMSCN) with α,β‐unsaturated amides and ketones, respectively, catalyzed by bifunctional mononuclear 1,1′‐bi‐2‐naphthol (BINOL)–Mg and binuclear bis(prophenol)–Mg catalysts was realized. A series of synthetically important 1,4‐cyano products were obtained with good to high enantioselectivities (up to 97 % ee).
实现了双官能单核1,1'-双-2-萘酚(BINOL)-Mg和双核双(前酚)-Mg催化剂分别催化三甲基甲硅烷基氰化物(TMSCN)与α,β-不饱和酰胺和酮的不对称氰化。获得了一系列具有重要至高对映选择性(高达97%ee)的重要的1,4-氰基合成产物 。
