摘要
The reaction of selenourea with diethyl 2,4-dibromo-3-oxoglutarate afforded ethyl 2-(2-amino-5-ethoxycarbonyl-1,3-selenazol-4-yl)-2-bromoethanoate. Treatment of the latter with acylating agents and various nucleophiles gave a series of new 4,5-disubstituted 2-amino-1,3-selenazoles. All compounds were characterized spectroscopically. The crystal structure determination of ethyl 2-(2-amino-5-ethoxycarbonyl-1,3-selenazol-4-yl)-2-bromoethanoate is reported.
