The bifunctionality of amino acids can be exploited by utilizing them as quenchers in rapid solution phase parallel synthesis. The amino group was used to covalently trap the excess electrophiles, whereas the carboxylic acid moiety was used to solubilize the derivatized amino acid in water. As a prototype we used potassium sarcosinate as a quencher for excess electrophiles in the acylation or sulfonation
氨基酸的双功能可以通过在快速溶液相平行合成中用作淬灭剂来加以利用。氨基用于共价捕获过量的亲电试剂,而羧酸部分用于将衍生的氨基酸溶解在水中。作为原型,我们使用肌氨酸钾作为N-甲基-苄胺的酰化或磺化中过量亲电试剂的猝灭剂。各种亲电试剂(例如酰氯,异氰酸酯和磺酰氯)已成功淬灭,以优异的收率得到纯净的产品。
