isothiazoline ring is reported. Nitroketene aminals 1 react with benzoyl isothiocyanate to form the adducts 3. These adducts can be converted to the 3,3-diamino-2-nitroacrylonitriles 2 in two discrete steps—first to an isothiazoline (4,7) by oxidation, and then to the nitriles by base-induced fragmentation; alternatively the adducts (3c, 11) can be directly treated with alkaline hydrogen peroxide to
据报道异噻唑啉环的新型断裂。硝基烯酮缩醛1与异硫氰酸苯甲酰反应形成加合物3。这些加合物可以通过两个不连续的步骤转化为3,3-二氨基-2-硝基丙烯腈2-首先通过氧化转化为异噻唑啉(4,7),然后通过碱诱导的裂解转化为腈;或者,可将加合物(3c,11)直接用碱性过氧化氢处理以一步得到腈。
