Tuning the organocatalyst: An unprecedented enantioselective intramolecular oxa‐Michael reaction of unactivated α,β‐unsaturated amides and esters catalyzed by a powerful hydrogen‐bond‐donating organocatalyst has been developed. Furthermore, the products obtained from this reaction have been used for the straightforward asymmetric synthesis of several natural products and biologically important compounds
调节有机催化剂:已开发出前所未有的对映体选择性分子内氧杂-Michael反应,该反应由强大的给氢键有机催化剂催化,未活化的α,β-不饱和酰胺和酯。此外,从该反应获得的产物已经用于几种天然产物和生物学上重要的化合物的直接不对称合成。
