报道了由乙烯基1,1-二酰基环丙烷快速简便地合成苯并环化的6,5-螺缩酮的方法。该方法利用温和的反应条件,具有良好至优异的产率和高的非对映选择性。然后使用该方法构建了伯克利酸的核心。
A rapid and facile synthesis of benzannulated 6,5-spiroketals from vinyl 1,1-diacylcyclopropanes is reported. The method utilizes mild reaction conditions with good to excellent yields and high diastereoselectivity. This methodology was then used to construct the core of berkelic acid.
