Thiols and amines were benzamidomethylated in water solution at room temperature with (benzamidomethyl)triethylammonium chloride (1) in the presence of a small quantity of triethylamine (pH>9). Benzamidomethyl thioethers (3a-d) and (benzamidomethyl) amines or di(benzamidomethyl)amines (5) were obtained in high yields (>90%) as well as S(CH2NHBz)2 in a reaction of 1 with Na2S. Benzamidomethyl esters RCOOCH2NHBz were obtained (60-75%) in reactions of carboxylic acids with 1 in chloroform or dioxane.
在室温下,
硫醇和胺在
水溶液中与(benzamidomethyl)三乙基
铵氯化物(1)反应,并存在少量
三乙胺(pH>9),进行了
苯酰胺甲基化反应。获得了高产率(>90%)的
苯酰胺甲基硫醚(3a-d)和(benzamidomethyl)胺或二(
苯酰胺甲基)胺(5),以及S(CH2NHBz)2,这是1与
Na2S反应的结果。在
氯仿或
二噁烷中,
羧酸与1反
应得到了
苯酰胺甲基酯RCOOCH2NHBz,产率为60-75%。
