All in one pot: an organocatalytic highly enantioselective synthesis of α-methylene-γ-lactones has been reported. The reaction between protected 2-hydroxymalonates and MBH carbonates is simply catalysed by chiral Lewis bases affording after acid treatment the corresponding lactones in excellent yields and enantioselectivities.
一切都在一锅中:已报道了α-亚甲基-γ-内酯的有机催化高度对映选择性合成。受保护的 2-羟基丙二酸酯和 MBH 碳酸酯之间的反应只需由手性路易斯碱催化即可,在酸处理后以优异的产率和对映选择性提供相应的内酯。
