  8-Substituted 3,4-dihydroquinolinones as a novel scaffold for atypical antipsychotic activity

  摘要：

  Several new, potent dopamine subtype 2 (DA D-2) active compounds with serotonin subtype 2A (5-HT2A) pharmacology are presented. 8-Substituted 3,4-dihydroquinolinones, tetrahydroquinolines, and N-acyl tetrahydroquinolines were evaluated in primary assays. Subtle changes on this novel scaffold translated to large changes in potency and selectivity in vitro. These compounds show promise as novel atypical antipsychotics for the treatment of schizophrenia. (c) 2005 Elsevier Ltd. All rights reserved.

  (from the condensation of 2-aminostyrenes with an aldehyde and subsequent nitration of the alkene) using a bifunctional thiourea catalyst and tert-butyl-Hantzsch ester leads to an intramolecular conjugate hydride addition nitro-Mannich reaction to give the corresponding cis-2-aryl-3-nitrotetrahydroquinolines as single diastereoisomers in high yields and enantioselectivities.

  A series of 2′-nitroisoflavones 8–10, 15, 22, 27 and 28 was prepared via the (2-nitro-phenyl)-acetic acids 1, 13, 19 and 25. In order to obtain the corresponding 2′-aminoisoflavones the reduction of 8–10, 15, 22, 27 and 28 was undertaken. Surprisingly, new 3-salicyloylindoles instead of the expected 2′-aminoisoflavones were the main reduction products. In the following paper the preparation of the

  日期：2008.5

  A novel protocol for the synthesis of indolone and quinolone derivatives from o-nitroaryl acids was developed using Zn and HCO2NH4 under supercritical fluid carbon dioxide (scCO2) medium. The process involves the reduction of the nitro group to an amino group followed by in situ cyclisation.
