experimental part, p. 1199 - 1201 (2010/04/22)
The N-methylation of electron-deficient pyrroles was affected using dimethyl carbonate in the presence of DMF and catalytic DABCO. This alkylation methodology has proven useful for the alkylation of a variety of pyrroles in 72-98% yields and is considered to be green chemistry relative to the more common use of methyl halides or dimethyl sulfate.
Synthesis of 4-cyano pyrroles via mild Knorr reactions with β-ketonitriles

, p. 899 - 904 (2012/12/23)
Mild methods for conducting Knorr chemistry with β-ketonitriles were developed. This enabled the preparation of 4-cyanopenta-substituted pyrroles and gave access to α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor potentiators for biol

Page/Page column 258-259, (2008/06/13)
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.
