In this article, we report the rapid and facile synthesis of chiral 3‐methyl‐2,5‐trans‐tetrahydrofurans. This reaction utilizes cheap and easily available starting materials. A domino hydrolysis and intramolecular Michael‐type ring closure reaction was the key step. As a result, synthesis of the desired 3‐methyl‐2,5‐trans‐tetrahydrofurans could be achieved in gram‐scale over seven linear steps with
在本文中,我们报告了快速,简便的手性3-甲基-2,5-反-四氢呋喃合成方法。该反应利用廉价且容易获得的起始原料。多米诺骨牌水解和分子内迈克尔型环闭合反应是关键步骤。结果,可以在七个线性步骤中以克级合成所需的3-甲基-2,5-反-四氢呋喃,具有高化学产率和高非对映选择性。
