Abstract: Some novel p-bromophenacyl-2,3-oxirane carboxylic esters were synthesized by Darzen′s condensation and esterification. The compounds were characterized by IR, 1H NMR spec-troscopy and clemental analysis. The antifungal activity of the compounds in vitro has been determined. It is foundthat, in general, the antifungal activity against Pellicularia Sasakii was higher than thatagainst Macyodhane Kawatasukai and Gibberella Zeae. p-Bromophenacyl-3, 3-pentamethy1ene-2, 3-oxiranepropanoic ester(2), p-bromophenacyl-3-(β-naphthyl)-2,3-oxiranepropanoicester(11)were the most effective which can completely inhibite the mycelial growth of P. Sasakil, M. Kawatsukai in amount of 100 ppm. p-Bromophenacyl-5-methyl-2,3-oxiranehexanoic ester(1) and p-bromophenacyl-3-(p-chlorophenyl)-2, 3-oxiranebutanoic ester(7) were highlyactive against P. Sasakii.
