在烷 (或芳 )胺和无水 DMF中加入 Cs2 CO3、碘化四丁铵 ,通过 CO2 鼓泡反应 1h,继而加入 1-溴 (或氯 )丁烷或 1-溴 - 3-苯基丙烷 ,再于室温 CO2 鼓泡反应 4～ 2 2 h,可得到相应的氨基甲酸酯 ,19例收率 4 7%～ 98%。底物改用氨基酸 ,反应同样顺利。氨基甲酸酯的有效合成@沈蓓苓 Cs 2 CO 3, tetrabutylammonium iodide were added to the alkane (or aryl) amine and anhydrous DMF, and the mixture was bubbled through CO 2 for 1 h followed by the addition of 1-bromo (or chloro) butane or 1-bromo- , And then at room temperature CO2 bubbling reaction 4 ~ 2 2 h, can be obtained corresponding carbamate, 19 cases of yield 47% ~ 98%. Substitution of amino acids, the reaction is equally smooth. The effective synthesis of carbamate @ Shen Beiling
