  日期：2007.11

  2-Amino-4-alkyl- and 2-amino-4-arylthiazole-5-carboxylates and their selenazole analogues were synthesized by α-halogenation of β-keto esters with N-bromosuccinimide, followed by cyclization with thiourea or selenourea, respectively, in the presence of β-cyclodextrin in water at 50 °C.

  2-氨基-4-烷基-和2-氨基-4-芳基噻唑-5-羧酸盐及其硒唑类似物是通过用N-溴代琥珀酰亚胺对β-酮酯进行α-卤化合成的，然后分别用硫脲或硒脲环化，在 50 °C 的水中存在 β-环糊精。
