Unprecedented Ullmann couplings of murrayafoline-A with either 6-bromo- or 4-bromocarbazole derivatives provide highly efficient synthetic routes to the biscarbazole alkaloids murrastifoline-A (6 steps, 66% overall yield) and bismurrayafoline-A (6 steps, 28% overall yield).
麦罗啡林 A 与 6-溴或 4-溴咔唑衍生物的空前 Ullmann 偶联反应,为双咔唑生物碱麦罗斯特非林 A(6 步,总收率 66%)和双麦罗啡林 A(6 步,总收率 28%)的高效合成提供了途径。
