Abstractmagnified imageAn efficient, organocatalytic enantioselective synthesis of N‐arylsulfonyl α‐amino nitriles from the corresponding α‐amido sulfones has been developed. This quinine‐catalyzed Strecker reaction provides the corresponding cyanated products in good yields and enantioselectivities.
Multiple Hydrogen‐Bonding Catalysts Enhance the Asymmetric Cyanation of Ketimines and Aldimines
A highly enantioselective cyanation of imines (up to >99 % ee) has been developed using well-designed C2-symmetric hydrogen bonding catalysts. This catalytic system is distinguished by its lowcatalystloading (S/C up to 1000), high efficiency, extremely broad substrate scope, scalability and mild reaction conditions.
使用精心设计的 C 2对称氢键催化剂开发了亚胺的高度对映选择性氰化(高达 >99 % ee)。该催化体系的特点是催化剂负载量低(S/C高达1000)、效率高、底物范围极广、可扩展性和反应条件温和。
