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.
不同取代的α-氰基环氧乙烷与硫脲反应生成了2-氨基噻唑啉酮衍生物2-氨基-5-(2,5-二甲氧基苯基)-1,3-噻唑-4(5H)-酮，C(11)H(12)N(2)O(3)S，(I)，以及2-氨基噻唑衍生物2-氨基-5-(2,5-二甲氧基苯基)-1,3-噻唑-4-羧酸乙酯，C(14)H(16)N(2)O(4)S，(II)。(II)中两个晶体学独立分子的几何形状几乎相同，但呈镜像关系。两种化合物的晶体结构均包含两种分子间氢键。
