Easily accessible N2-acyl derivatives of 2-aryl-5-hydrazino-1,3- oxazole-4-carbonitriles react peculiarly with the Lawesson reagent. In addition to thionation, the reaction involves a recyclization to afford new substituted 2-(5-amino-1,3-thiaz

Acylation products of 2-aryl-5-hydrazino-4-X-1,3-oxazoles [X = C(O)OAlk, P(O)(OAlk)2], when heated in acetic acid or ethanol, undergo recyclization and transform into the derivatives of 1,3,4-oxadiazol-2-ylglycine or its phosphonyl analog. A si
