methods for the synthesis of carbamates, N,N′-unsymmetrically disubstituted ureas, and S-alkyl thiocarbamates derived from CH3OC(O)SNCO in one-step are provided. Reactions are operationally simple and have high selectivity toward nitrogen, oxygen, and sulfur nucleophiles. The absence of solvents coupled with high yields and short reaction times make these procedures very attractive for synthesis.
提供了一种方便,简单,合适的方法,可一步合成合成氨基甲酸酯,N,N'-不对称双取代尿素和CH 3 OC(O)SNCO衍生的S-烷基硫代氨基甲酸酯。反应操作简单,对氮,氧和硫亲核试剂具有高选择性。缺少溶剂,再加上高产率和短反应时间,使得这些方法对于合成非常有吸引力。
