A new approach to synthesis of a series of 3-carboxamidine iminocoumarins derivatives and substituted benzopyrano[2,3-d]pyrimidines was developed. The chemical structure of all the compounds was investigated by infrared, 1H NMR, 13C NMR, mass, and elemental analysis. The anticholinesterase activity of compound 12 was evaluated according to the modified Ellman’s method. 相似文献
