The present invention is directed to dipyrazole compounds of formula I and their pharmaceutically acceptable salts, stereoisomers, tautomers, or solvates thereof. Novel compounds include those of formula I.
The compounds of this invention modulate AMPA and NMDA receptor function, and therefore are useful as pharmaceutical agents, especially for the treatment of neuropsychiatric disorders.
Abstract A one-pot route was developed for efficient synthesis of novel 2-substituted quinolin-4-carboxamides via a four-component sequential reaction between isatins, ammonium acetate, triethyl orthoacetate, and 4-hydroxycoumarin or 4-hydroxy-6-methyl-2H-pyran-2-one. This protocol is an extension of Pfitzinger’s quinoline synthesis and involves an unprecedented in situ iminoacetylation of 2H-pyrone
