have been synthesized directly from the corresponding unprotected sugars and dithiocarbamate salts in good yields by using 2-chloro-1,3-dimethylimidazolinium chloride (DMC) as condensing agent in aqueous media. The three-component one-pot synthesis of GDTCs starting from unprotected sugars, carbon disulfide, and secondary amines has also been successfully demonstrated. This is the first report on the
使用2-氯-1,3-二甲基咪唑啉鎓氯化物(DMC)作为缩合剂在水性介质中,可以直接从相应的未保护糖和二硫代氨基甲酸盐以高收率直接合成糖基二硫代氨基甲酸酯(GDTC)。还已经成功地证明了从未保护的糖,二硫化碳和仲胺开始的三组分一锅法合成GDTC。这是有关不使用任何保护基团由未保护的糖直接合成GDTC的首次报道。
