(EN) A class of tryptamine analogues bearing an optionally substituted phenyl nucleus at the 2-position are selective antagonists of the human 5-HT2A receptor and are therefore useful as pharmaceutical agents, especially in the treatment and/or prevention of adverse neurological conditions, including psychotic disorders such as schizophrenia.(FR) L'invention concerne une catégorie d'analogues de tryptamine comprenant un noyau phényle éventuellement substitué en position 2, lesquels analogues constituent des antagonistes sélectifs du récepteur 5-HT2A humain et sont, par conséquent, utiles en tant qu'agents pharmaceutiques, en particulier dans le traitement et/ou la prévention d'états neurologiques indésirables, y compris de troubles psychotiques tels que la schizophrénie.
InBr<sub>3</sub>-Catalyzed Friedel−Crafts Addition of Indoles to Chiral Aromatic Epoxides: A Facile Route to Enantiopure Indolyl Derivatives

Graphene oxide efficiently promotes high regio‐ and enantioselective ringopeningreactions of aromatic epoxides by indoles addition, in solvent‐ and metal‐free conditions. The Friedel–Crafts products were obtained with enantioselectivity up to 99 % ee. The complete inversion of stereochemistry indicates the occurrence of SN2‐type reaction, which assures high level of enantioselectivity.
在无溶剂和无金属的条件下,通过添加吲哚,氧化石墨烯可有效促进芳香族环氧化物的高区域和对映选择性开环反应。获得的Friedel-Crafts产品的对映选择性高达99%ee。立体化学的完全逆转表明发生了S N 2型反应,从而确保了高水平的对映选择性。
