An asymmetric synthesis of elusive chiral cyclopentadienes has been developed by gold(I)‐catalyzed alkoxycyclization of 1,3‐dien‐5‐ynes. The application of these substrates in completely diastereoselective Diels–Alder cycloaddition reactions, which can be carried out in one pot from achiral 1,3‐dien‐5‐ynes, allows the preparation of highly functionalized products bearing five stereogenic centers with
金(I)催化的1,3-二烯基-5-炔烃的烷氧基环化反应已开发出一种难以捉摸的手性环戊二烯的不对称合成方法。这些底物在完全非对映选择性Diels-Alder环加成反应中的应用(可以从一个非手性1,3-dien-5-ynes在一锅中进行),可以制备带有五个对映异构体过量的立体中心的高度官能化产物。
