Recent advances on the synthesis and application of tetrahydro-γ-carbolines

引用

Chinese Chemical Letters 2023年第12期34卷 119-136页

作者： Haibo Mei Klára Aradi Loránd Kiss Jianlin Han Jiangsu Co-Innovation Center of Efficient Processing and Utilization of Forest Resources Nanjing Forestry University Institute of Organic Chemistry Research Centre for Natural Sciences Stereochemistry Research Group

Tetrahydro-γ-carbolines(THγ Cs) constitute one of the most important subtypes of indole alkaloids. In addition to being substructures of natural products, these structural motifs and moieties can often be found in pharmaceuticals due to their diverse bioactivities such as antiviral, antibacterial, antifungal,antiparasitic, antitumor, anti-inflammatory, and neuropharmacological activities. Beyond the pharmacological and biological aspects of these scaffolds, they have considerable synthetic applications for the construction of further bioactive compounds, too. The aim of this review is to summarize recent developments in the synthesis of this compound class.

Recent Developments in Benzoannelated Triquinacenes and Fenestranes

引用

复旦学报（自然科学版） 2007年第5期46卷 773-页

作者： D.Kuck J.Strübe J.Linke Department of Chemistry Bielefeld University33615 BielefeldGermany

1 Results Introduction of functional groups at the frameworks of the centropolyindanes is a non-trivial task since the construction of the rigid and massive skeletons of,e.g.,tribenzotriquinacene and fenestrindane requires well-balanced synthesis strategies[1,2].In the present contribution,some selected examples are presented for the recent multiple functionalization of tribenzotriquinacenes,such as compound 1,and fenestrindanes,such as compound 2,preformed in our *** Fig.1.
