A novel route to functionalized carbazoles utilizing a tandem Suzuki cross-coupling/SNAr protocol is described. This process was found to be compatible with a variety of electron-withdrawing groups including aldehydes, esters, and sulfones. Using this method, a concise total synthesis (four steps, 50% overall yield) of the carbazole alkaloid glycosinine was achieved.
描述了使用串联铃木交叉偶联/ SNAr方案的功能化咔唑的新途径。发现该方法与包括醛,酯和砜在内的多种吸电子基团相容。使用该方法,可以实现咔唑生物碱糖苷的简明全合成(四个步骤,总收率50%)。
