The areno(e)indols have the formula (I). The methods comprises: (a) reacting (VI) with an aldehyde Ar''-CHO to obtain (VII); (b) oxidizing (VII) to yield the cetone (VIII); (c) reating (VIII) with a strong base and thereafter with an acyle chloride CICOR, to produce (IX); (d) subjecting to a photochemical cyclization (IX) to produce (I). In said formulas Ar is phenyl or substituted phenyl; Ar' is a radical (i) or )ii); R is an acyle group, Ar'' is a phenyl, pyrolyl, furanyl or thiophenyl group substituted up to three times by any of the radicals R, R¹, R², or R³. The compounds (I) are useful as intermediates in the synthesis of hexahydroareno(e)cyclopropa(c)indol-4-ones with antitumoral activity.
壬(e)吲哚具有式(I)。方法包括:(a) (VI) 与醛 Ar''-CHO 反应,得到 (VII);(b) 氧化 (VII),得到酮 (VIII);(c) (VIII) 与强碱再反应,然后与酰基氯 CICOR 反应,得到 (IX);(d) 对 (IX) 进行光化学环化反应,得到 (I)。在上述式子中,Ar 是苯基或取代苯基;Ar'是基(i)或)ii);R 是酰基,Ar''是被 R、R¹、R² 或 R³ 中的任一基取代最多三次的苯基、吡咯基、呋喃基或噻吩基。化合物 (I) 可用作合成具有抗肿瘤活性的六氢areno(e)cyclopropa(c)indol-4-酮的中间体。
