3-aminoselenophenes (using thiophosgene). Those compounds were then converted to the corresponding thioureas in the presence of ammonium hydroxide. Cyclization in 2-aminoselenolo[3,2-d]thiazoles was achieved using DDQ. 2-Aminothieno[3,2-d]thiazoles were obtained from 3-isothiocyanatothiophenes using the same pathway.
在这项工作中,我们描述了从3-氨基硒吩(使用硫光气)开始的3-isothiocyanatoselenophenes的合成。然后在氢氧化铵存在下将那些化合物转化为相应的硫脲。使用DDQ在2-氨基硒代[3,2- d ]噻唑中环化。使用相同的途径从3-异硫氰酸根合噻吩获得2-氨基噻吩并[3,2- d ]噻唑。
