Reinvestigation of Rearrangement of Benzodiazepinediones into Quinoleines Under Microwave or Conventional Heating Conditions
摘要:
Microwave or conventional heating of pyrrolo and pyrido[2,1-c][1,4]benzodiazepines in boiling phosphorus oxychloride led to rearranged products like benzo[h][1,6]naphthyridine and azepino[3,2-c]quinoleine and not to cyclopenta[b] [1,6]benzodiazepin and tetrahydrodibenzo[b,f][1,4]diazepine as initially described.

La présente invention a pour objet des imino-éthers de benzo[h][1,6]naphtyridines et d'azépino[3,2-c] quinoléines, ainsi que leurs sels et éventuels isomères et mélanges d'isomères. Elle a également pour objet l'application thérapeutique de ces dérivés et sels, notamment en tant que médicament antagoniste vis-à-vis de la réponse produite par la sérotonine et de médicament antidépresseur ou destiné aux traitements des troubles mnésiques.

New Benzo[<i>h</i>][1,6]naphthyridine and Azepino[3,2-<i>c</i>]quinoline Derivatives as Selective Antagonists of 5-HT<sub>4</sub> Receptors: Binding Profile and Pharmacological Characterization
A series of benzo[h][1,6]naphthyridine and azepino[3,2-c]quinolinederivatives were prepared and evaluated to determine the necessary requirements for high affinity on the 5-HT(4) receptors and high selectivity versus other receptors. The compounds were synthesized by substituting the chlorine atom of benzonaphthyridines and azepinoquinolines with various N-alkyl-4-piperidinylmethanolates. They were
