An organic base-promoted chemoselective alkylation of lenalidomide with different halides was developed, which offers a novel approach to a highly functionalized lenalidomide-based PROTAC library under mild reaction conditions. DIPEA was found to act as an efficient base to trigger facile generation of arylamine alkylation products compared with inorganic bases. This library was successfully applied
开发了一种用不同的卤化物对来那度胺进行有机碱促进的化学选择性烷基化反应,这为在温和的反应条件下以高度功能化来那度胺为基础的PROTAC库提供了一种新颖的方法。与无机碱相比,发现DIPEA是触发芳基胺烷基化产物容易生成的有效碱。该文库已成功应用于BET PROTAC,不仅可以降解BET蛋白,而且还可以有效抑制癌细胞的增殖。
