An efficient procedure was developed for the synthesis of previously unknown 3-aryl(styryl)-2-(4-arylthiazol-2-yl)oxirane-2-carboxamides and 2-(4-arylthiazol-2-yl)-1-oxaspiro[2.5]octane-2-carboxamides based on treatment of (E)-3-aryl-2-(4-arylthiazol-2-yl)acrylonitriles and cyclohexylidene(4-arylthiazol-2-yl)acetonitriles with an H2O2—KOH system in EtOH. Oxidation of (E)-3-(4-chlorophenyl)-2-(4-ph
