The cyclopenta[b]indole moiety represents a key skeletal unit in several natural and synthetic compounds that exhibit diverse biological properties. We described herein a two-step sequence for synthesizing cyclopenta[b]indoles with great structural diversity in overall yields up to 37%. The key step was a palladium-catalyzed oxidative annulation of 3-alkylindoles (Fujiwara–Moritani reaction). The obtained
环戊[ b ]吲哚部分代表几种天然和合成化合物的关键骨架单元,这些化合物表现出多种生物学特性。我们在本文中描述了用于合成具有巨大结构多样性的环戊并[ b ]吲哚的两步序列,总产率高达37%。关键步骤是钯催化的3-烷基吲哚的氧化环化反应(藤原-莫里塔尼反应)。所获得的环戊[ b ]吲哚被用作非均相氢化反应的底物,从而以中等收率提供了新的熔融二氢吲哚。三个这样的二氢吲哚的酸催化的分子内环化反应以89%,90%和61%的收率得到四环内酰胺。

The structure–activity relationship (SAR) for three series of lactam-fused chroman derivatives possessing 3-amino substituents was evaluated. Many compounds exhibited affinities for both the 5-HT1A receptor and the 5-HT transporter. Compounds 45 and 53 demonstrated 5-HT1A antagonist activities in the in vitro cAMP turnover model.
The Gewald three-component reaction yielding highly substituted 2-aminothiophene heterocycles has been known for a long time and holds an extraordinary potential in the pharmaceutical industry. Herein, we describe a four-component reaction initiated by the conjugate addition of different indolederivatives to α,β-unsaturated carbonyl compounds. This is followed by an in situ Gewald three-component
