A reaction of 1,2,3-thiadiazole-4-carbaldehyde with 3-aminobenzo-15-crown-5 involves the Cornforth rearrangement of the 1,2,3-thiadiazole ring, which leads to 1,2,3-triazole-4-carbothioamide containing the benzocrown ether substituent in position 1 of the triazole ring. Reversible formation of the isomeric thiadiazole occurs in aprotic nonpolar solvents such as deuterated chloroform. These compounds
1,2,3-噻二唑-4-甲醛与 3-氨基苯并-15-冠-5 的反应涉及 1,2,3-噻二唑环的 Cornforth 重排,这导致 1,2,3-三唑-在三唑环的 1 位含有苯并冠醚取代基的 4-硫代碳酰胺。异构噻二唑的可逆形成发生在非质子非极性溶剂如氘代氯仿中。这些化合物适用于从水相中提取 α-氨基酸。
