A facile synthesis of beta-functionalized gamma-hydroxybutenolides was achieved using a Baylis-Hillman reaction followed by singlet oxygen oxidation. The conversion from 3-furfural was regio- and diastereoselective. [reaction: see text].
使用Baylis-Hillman反应,然后进行单线态氧氧化,可以轻松合成β-官能化的γ-羟基
丁烯内酯。
3-糠醛的转化具有区域选择性和非对映选择性。[反应:请参见文字]。
