We describe an efficient new approach for the synthesis of a chiral butenolide that is based on the oxidation of a chiral furan ring with singlet oxygen in the presence of Hünig’s base, followed by Luche reduction and in situ lactonization.
我们描述了一种有效的新方法,用于合成手性丁烯内酯,该方法基于在Hünig碱存在下用单线态氧氧化手性呋喃环,然后进行Luche还原和原位内酯化。
