[2-[(四氢-2H-吡喃-2-基)氧]乙基]二硫代氨基甲酸甲酯

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To a solution of N-(2-hydroxyethyl)dithiocarbamic acid methyl ester (81.7 g) in dichloromethane (300 ml) are added dihydropyran (54 g) and toluene-p-sulfonic acid monohydrate (1.0 g), and the mixture is stirred for 1 hour. The reaction mixture is poured in aqueous sodium hydrogen carbonate, shaken and the resulting organic layer is separated. The layer is concentrated under reduced pressure to give N-[2-(2-tetrahydropyranyl)oxyethyl]dithiocarbamic acid methyl ester (129 g). shaken the resulting organic layer is separated The layer is concentrated under reduced pressure
