摘要
以PEG-400为相转移催化剂,由氯甲酸乙酯与2-氨基-5-芳氧亚甲基-1,3,4-噻二唑反应,合成了新型的N-(5-芳氧亚甲基-1,3,4-噻二唑-2-基)氨基甲酸乙酯.目标产物的结构经元素分析、IR及1HNMR得到了确证.该方法具有反应条件温和、操作简便、产率高等优点.
Ethyl N-(5-aryloxymethylene-1,3,4-thiadiazol-2-yl) carbamates were efficiently synthesized by the reactions of 2-amino-5-aryloxymethylene-1,3,4-thiadiazoles with ethyl chlorocarbamate under liquid-liquid phase transfer catalysis using PEG-400 as catalyst, with advantages of mild condition, easy handling, and high yield. The structures of compounds were characterized by elemental analyses, IR and ()~1HNMR.
