Methyl esters of 2-aminotetrahydrobenzothiophene-3-carboxylic acids decorated with trifluoromethyl-containing heterocycles

详细

Methyl 2-aminothiophene-3-carboxylates were modified with trifluoromethyl-containing five-membered heterocycles by cyclocondensation of methyl trifluoropyruvate N-thiophen-2-ylimines with 1,3-N,N-binucleophiles (2-aminothiazoline and benzamidines) to obtain the corresponding 5-oxo-6-trifluoromethyl-2,3,5,6-tetrahydroimidazoles and 5-oxo-2-phenyl-4-trifluoromethyl-4,5-dihydro-1H-imidazoles. Radioligand binding was used to study the in fluence of the synthesized compounds on the neuronal NMDA receptors.
