A total synthesis of carbazomycin G (1) has been newly completed in seven steps. The 1,3-dioxygenated carbazole (4) via the 3-methoxy-1-methoxymethyloxycarbazole (11) as a synthetic precursor was synthesized by using the allene-mediated electrocyclic reaction of a 6π electron system generating from the 2-propargylindole derivative (10), which was derived from the 3-vinylindole (8) in three steps. Finally
卡巴霉素G(1)的总合成已通过七个步骤新近完成。通过使用由2-丙炔基吲哚衍生物(10)产生的6π电子系统的烯丙基介导的电环反应,合成了通过3-甲氧基-1-甲氧基甲基氧基咔唑(11)作为合成前体的1,3-二加氧咔唑(4)。),它是通过3个步骤从3-乙烯基吲哚(8)衍生而来的。最后,苯酚(4)的氧化,然后向咔唑-1,4-醌(3)中加入甲基锂,得到咔唑霉素G(1)。
