酯基是羧酸衍生物中酯的官能团，-COOR（R一般为烷基等其他非H基团），英文名称为ester group，酯基主要发生水解反应。
异氰酸酯基 NCO ; isocyanate group ; QQNCO
氨基甲酸酯基团 NHCOO
乙酯基 [有化] carbethoxy ; ethoxycarbonyl group
氨基甲酸酯基 urethane group ; urethane link ; NHCOO
甲酯基 [有化] carbomethoxy ; methoxycarbonyl group
转酯基酌 transesterification
氨酯基 NHCOO ; urethano
烷酯基 carbalkoxy
酯基硫醇锡 esterthio tin stabilizer ; dialkyltin mercaptide
In addition, the benzylic cyano group in such substrates can be replaced by an ester group, which makes the method applicable to the synthesis of N-aryl or N-alkyl-indole-3-carboxylic ester derivatives.
此外,底物中苄位的氰基还可以替换为酯基,从而使该方法还可以用来合成N-取代(芳基或烷基)-吲哚-3-羧酸酯类衍生物。
