title: 2-aminothiazole and 2-aminothiazolinone derivatives.
abstract: The reaction of different substituted alpha-cyanooxiranes with thiourea resulted in the formation of the 2-aminothiazolinone derivative 2-amino-5-(2,5-dimethoxyphenyl)-1,3-thiazol-4(5H)-one, C(11)H(12)N(2)O(3)S, (I), and the 2-aminothiazole derivative ethyl 2-amino-5-(2,5-dimethoxyphenyl)-1,3-thiazole-4-carboxylate, C(14)H(16)N(2)O(4)S, (II). The geometries of the two crystallographically independent molecules in (II) are nearly identical but mirror related. The crystal structures of both compounds contain two types of intermolecular hydrogen bonds.
