The adducts formed by 4-functionally-substituted 2-aryl-5-hydrazino-1,3- oxazoles and aryl isothiocyanates recyclize on heating to produce the hitherto unknown derivatives of (1,3,4-thiadiazol-2-yl)glycine and its phosphonyl analogue.

On the basis of methyl esters of 2-aryl-5-hydrazino-1,3-oxazole-4- carboxylic acids the earlier unknown methyl esters of 2-aryl-5-(3,5-dimethyl-1H- pyrazol-1-yl)-1,3-oxazole-4-carboxylic acids as well as their functional derivatives were synthesized. The latter were used for further transformations, in particular, for introducing the residues of highly basic aliphatic amines into the 5 position of oxazole, and the oxazol-2-yl moiety into the 4 position of the oxazole ring.

Transformations of acylation products of functionally 4-substituted 2-alkyl(aryl)-5-hydrazino-1,3-oxazoles into 1,3,4-oxadiazole derivatives

, p. 425 - 431 (2007/10/03)
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
