Metal-free, thermally promoted synthesis of 3-alkoxy-3-alkoxycarbonyl-2-azetidinones via the Wolff-Staudinger β-lactam synthesis using dialkyl diazomalonates is described. The reaction appears fairly general and delivers only one diastereomer.

无过渡金属、热促进、非对映选择性 Wolff β-内酰胺合成中的二烷基重氮丙二酸酯

描述了使用重氮丙二酸二烷基酯通过 Wolff-Staudinger β-内酰胺合成法合成 3-alkoxy-3-alkoxycarbonyl-2-azetidinones 的无金属热促进合成。该反应看起来相当普遍,并且仅产生一种非对映异构体。
