The reaction of 5-aryl-2-arylideneamino-1,3,4-oxadiazoles (5a-d) with trichloroacetic acid followed by ring closure of the isolable intermediates, 5-aryl-2--1,3,4-oxadiazoles (6a-d), with dipeptides (gly.gly and L-ala.gly) yields new 2,6-diaryl-5-peptidyl (gly.gly and L-ala.gly)imino-5,6-dihydroimidazo--1,3,4-oxadiazoles.Two of the compounds (8d and 8h) displayed the in vitro fungitoxicity equivalent to that of a commercial fungicide Mancozeb against A. solani and F. oxysporum at 1000 ppm concentration. - Key words: 1,3,4-oxadiazoles/imidazoles/imidazo-oxadiazoles; petidylimino; the in vitro fungitoxicity
