A metal-free and two-phase protocol for the Meyer-Schuster isomerization of propargyl alcohols to the corresponding α,β-unsaturated carbonyl compounds has been achieved in the presence of stoichiometric phosphorous acid aqueous solution, which produces the desired products in high yields with excellent stereoselectivity. Compared with the traditional methods, the procedure features broad scope of the
在化学计量的亚磷酸水溶液的存在下,已实现了炔丙醇Meyer-Schuster异构化为相应的α,β-不饱和羰基化合物的无金属两相方案,该方案可高收率地生产所需产物出色的立体选择性。与传统方法相比,该方法具有底物范围广,条件温和且易于分离的特点,是Meyer-Schuster反应的有吸引力的替代方法。
