The synthesis of the new heterocycle 1,3,4-selenadiazin-2-one is described, based on the preparation of the analogue heterocycle 1,3,4-thiadiazin-2-one. The related cyclization between an α-haloketone and a thiocarbazate cannot readily be employed within the selenium series. Therefore a new route was developed based upon a diazotization/hydrolysis sequence of the related 2-amino-1,3,4-selenadiazine
基于类似物杂环1,3,4-噻二嗪-2-one的制备,描述了新的杂环1,3,4-硒二嗪-2-one的合成。在硒系列中,α-卤代酮和硫代氨基甲酸酯之间的相关环化作用不容易采用。因此,基于相关的2-氨基-1,3,4-硒代二嗪的重氮化/水解序列,开发了一种新的途径。
