Better in pairs: A highly efficient asymmetric reaction of salicylic aldehydes with cyclohexenones by means of a domino oxa‐Michael–Mannich pathway has been achieved by using novel dual organocatalytic ion‐pair assemblies from pyrrolidines and readily available primary amino acids (see scheme).
更好的配对:通过使用吡咯烷和容易获得的伯氨基酸的新型双有机催化离子对组件,通过多米诺oxa-Michael-Mannich途径实现了水杨醛与环己烯酮的高效不对称反应(参见方案)。
