采用亲核有机催化剂(Fc-PIP)催化一系列埃农酸的分子内Michael加成-内酯化多米诺反应,合成了顺式-2,3-二氢苯并呋喃衍生物,具有良好的对映选择性(94%-98%ee)和非对映选择性(高达99/1).
A highly enantioselective intramolecular Michael addition‐Lactonization domino reaction of a range of enon acids catalyzed by nuleophilic organocatalyst (Fc‐PIP) was developed, furnishingcis‐2,3‐dihydrobenzofuran derivatives with excellent enantioselecitivities (94%–98%ee) and good diastereoselectivities (up to 99/1).
