A new type of chiral bicycle imidazole nucleophilic catalyst was rationally designed, facilely synthesized, and successfully applied in an asymmetric Steglich rearrangement with good to excellent yield and enantioselectivity at ambient temperature. Moreover, it can be easily recycled with almost no reduction of catalytic efficiency. This is the first example for the successful chiral imidazole nucleophilic
一种新型手性双环
咪唑亲核催化剂经过合理设计、简便合成,并成功应用于不对称 Steglich 重排,在室温下具有良好的产率和对映选择性。此外,它可以轻松回收,几乎不会降低催化效率。这是没有氢键辅助的手性
咪唑亲核催化剂成功的第一个例子。
