3-hydroxy-4-(trifluoromethyl)azetidin-2-ones proved to be interesting substrates for the synthesis of novel 3-[2,2,2-trifluoro-1-(arylamino)ethyl]-1,4-dioxan-2-ones via intramolecular cyclization of 3-(2-hydroxyethoxy)-β-lactam intermediates. 3-Hydroxy-4-(trifluoromethyl)azetidin-2-ones were synthesized from the corresponding 3-benzyloxy-β-lactams and successfully transformed into new 3-chloro-4-(trifluor
摘要 从相应的3-苄氧基-β-内酰胺合成3-羟基-4-(三氟甲基)氮杂环丁烷-2-酮,并将其成功转化为新的3-氯-4-(三氟甲基)氮杂环丁烷-2-酮结构单元。已显示后者的氯化物是用于构建含CF 3的氨基丙烷,1,3-恶嗪酮,1,3-恶二嗪-2-酮和氮丙啶的合格前体。此外,3-羟基-4-(三氟甲基)氮杂环丁烷-2-酮被证明是合成新型3- [2,2,2-三氟-1-(芳氨基)乙基] -1,4-的有趣底物。二恶烷-2-酮通过3-(2-羟基乙氧基)-β-内酰胺中间体的分子内环化作用。 从相应的3-苄氧基-β-内酰胺合成3-羟基-4-(三氟甲基)氮杂环丁烷-2-酮,并将其成功转化为新的3-氯-4-(三氟甲基)氮杂环丁烷-2-酮结构单元。已显示后者的氯化物是用于构建含CF 3的氨基丙烷,1,3-恶嗪酮,1,3-恶二嗪-2-酮和氮丙啶的合格前体。此外,3-羟基-4-(三氟甲基)氮杂环丁烷-2-酮被证明是合成新型3-
