A procedure for enantioselective organocatalytic conjugate additions of a variety of N-heterocycles to α,β-unsaturated enone systems is presented. The reactions are efficiently catalyzed by salts of 9-amino-9-deoxy-epiquinine (3d). Cyclic, acyclic, and aromatic enones can be used in reactions with 1H-benzotriazole (1a) or 5-phenyltetrazole derivatives 12, providing the Michael addition products in
介绍了将各种 N-杂环对映选择性有机催化共轭加成到 α,β-不饱和烯酮系统的过程。该反应由 9-氨基-9-脱氧-表奎宁 (3d) 的盐有效催化。环状、无环和芳族烯酮可用于与 1H-苯并三唑 (1a) 或 5-苯基四唑衍生物 12 的反应,以高产率提供迈克尔加成产物,并具有良好的对映选择性。
