In this study, N-substituted 2-formylaminoarylacetamides (3) were obtained by he Ugi four-component reaction between isocyanides (1), aldehydes (2), and ammonium formate. The reaction products (3) were dehydrated with POCl-3/NEt-3 to give the title compounds (4). The structure of the compounds 3 and 4 was confirmed by spectral data and elemental analysis. Tests of antimicrobial activity showed that compounds 4 were ineffective against Escherichia coli and fairly active against Klebsiella pneumoniae and Staphylococcus aureus. A better activity was shown against Bacillus subtilis, but all the tested compounds showed a very good inhibitory effect against Candida albicans.
