Chirality Control by Substituents in the Asymmetric Addition of Et<sub>2</sub>Zn to Aromatic Aldehydes Catalyzed by<i>cis</i>-(1<i>R</i>,2<i>S</i>)-2-Benzamidocyclohexanecarboxylic Acid Derived 1,3-Aminoalcohols
A series of novel opticallyactive 1,3‐aminoalcohols based on cis‐(1R,2S)‐2‐benzamidocyclohexanecarboxylic acid and trans‐(1R,2R)‐2‐benzamidocyclohexanecarboxylic acid were synthesized and used in the asymmetric diethylzinc addition to aromatic aldehydes. Not only the enantioselectivity but also the stereochemistry of the product were controlled by the N‐substituents and the substituents on the vicinity
