esters is demonstrated. This protocol efficiently installs various tertiary or secondary alkyl fragments onto the nitrogen atom of azole nucleophiles under mild and transition-metal-free conditions. The pyridinium additive successfully inhibits the formation of elimination byproducts from the carbocation intermediate. This reaction is applicable to the synthesis of a protein-degrader-like molecule
展示了唑亲核试剂和脂肪族羧酸衍生的氧化还原活性酯之间的有机光氧化还原催化脱羧交叉偶联。该协议在温和和无过渡金属的条件下有效地将各种三级或二级烷基片段安装到唑亲核试剂的氮原子上。吡啶鎓添加剂成功地抑制了碳阳离子中间体消除副产物的形成。该反应适用于合成含有唑类和沙利度胺的类蛋白质降解分子。
