以吲哚(3)为起始原料,以2,3-二溴-1-甲基吲哚(5)为起始原料,一步合成了红藻布氏凹顶藻(Laurencia brongniartii)和脆星Ophiocomaerinaceus代谢产物2,3,6-三溴-1-甲基吲哚(1)和2,3,5,6-四溴-1-甲基吲哚(2),产率92%。此外,1和5均可合成2,产率分别为67%和65%。
The red algaLaurencia brongniartiiand brittle starOphiocomaerinaceusmetabolites 2,3,6-tribromo-1-methylindole (1) and 2,3,5,6-tetrabromo-1-methylindole (2) are easily synthesized selectively from 2,3-dibromo-1-methylindole (5), which in turn is prepared from indole (3) in one continuous sequence in 92% yield. Moreover,2can be made from both1and5in 67% and 65% yields, respectively.
