The present invention relates to pyrrole and pyrazole compounds of formula (I) and their pharmaceutically acceptable salts, and further relates to their use in treating schizophrenia, cognitive deficits associated with schizophrenia, Alzheimer's disease, dementia of the Alzheimer's type, mild cognitive impairment, or depression. The compounds act as potentiators on glutamate receptors, in particular AMPA and the GluR family.

Mild methods for conducting Knorr chemistry with β-ketonitriles were developed. This enabled the preparation of 4-cyano-penta-substituted pyrroles and gave access to α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor potentiators for biological evaluation. In addition, a series of alkyl and aryl β-ketonitriles were employed in Knorr cyclizations to probe steric tolerance and the possibility

Diverse functionalized quinoxalines were synthesized in good yields from arylamines and readily available β-keto oximes through condensation and metal-free N-arylation. The reaction was compatible with various functional groups, such as halides, cyano, and esters. A mechanism was proposed based on the experimental results. These quinoxalines were easily obtained on a gram scale and converted to various
