A facilenew one pot annulation of monobromoquinones 7 to the vinylogous carbamate 3 provides a direct route to the pyrroloindoloquinone framework. Synthesis was extended to 7-methoxymitosene 2 ( R = OMe, R1 = R2 = 11). The mechanism of the annulation was elucidated.
一种新的一锅法将单溴代醌7与乙烯基氨基甲酸酯3环化,可提供直接通往吡咯并吲哚醌骨架的途径。合成扩展至7-甲氧基米托烯2(R = OMe,R 1= R 2= 11)。阐明了环空的机理。
