已经使用涉及α,β-二氢吲哚的分子内闭环的新方法合成了许多环戊二烯基[B]吲哚-1-酮以及-3-酮。β-的不饱和酰基吲哚。在某些情况下,得到1,2,3,4-四氢咔唑-4-酮。该方法已用于吲哚生物碱越楚克烯和咔唑生物碱类似物脱甲氧基咔唑霉素B的合成。
A number of cyclopent[b]indol-1-ones as well as -3-ones have been synthesized, using a new methodology involving intramolecular ring closure of .alpha.,.beta.-unsaturated acylindoles. In some cases 1,2,3,4-tetrahydrocarbazol-4-ones were obtained. This methodology was used in the syntheses of the indole alkaloid yuehchukene and the carbazole alkaloid analogue demethoxycarbazomycin B.
