Depending on the reaction conditions, the reactions of (E)-3,3,3-trichloro-1-nitropropene with cyclohexanone enamines led to bicyclo[4.2.0]octanes or trisubstituted enamines, which are the ring-chain tautomers capable of reversible transformations. Diastereoselectivity of the reactions of (E)-3,3,3-trichloro(trifluoro)-1-nitropropenes with cycloalkanone enamines were studied, a series of hitherto unknown
根据反应条件,(E)-3,3,3-三氯-1-硝基丙烯与环己酮烯胺反应生成双环[4.2.0]辛烷或三取代烯胺,它们是能够可逆的环链互变异构体转换。研究了(E)-3,3,3-三氯(三氟)-1-硝基丙烯与环烷酮烯胺反应的非对映选择性,合成了一系列迄今未知的含CX3的硝基烷基化烯胺和γ-硝基酮,其结构式为通过核磁共振光谱和X射线衍射确定了新化合物。
