heterocyclic, alicyclic, and polysubstituted compounds. Here, we report a robust stereocontrolled procedure for the synthesis of novel functionalized trifluoromethyl-containing piperidine and azepane derivatives, based on oxidative ring cleavage of the C=C bond of diversely substituted cycloalkenes, followed by reductive ring closure of the diformyl intermediates in the presence of fluorine-containing amines
摘要 官能化的二醛被认为是重要的底物,可以转化为各种取代的杂环,脂环族和多取代的化合物。在此,我们报告了一种稳健的立体控制程序,该程序基于各种取代的环烯烃的C = C键的氧化环裂解,然后在存在的情况下,对二甲酰基中间体进行还原性闭环,从而合成了新型功能化的含三氟甲基的哌啶和氮杂环丙烷衍生物含氟胺。 官能化的二醛被认为是重要的底物,可以转化为各种取代的杂环,脂环族和多取代的化合物。在此,我们报告了一种稳健的立体控制程序,该程序基于各种取代的环烯烃的C = C键的氧化环裂解,然后在存在的情况下,对二甲酰基中间体进行还原性闭环,从而合成了新型功能化的含三氟甲基的哌啶和氮杂环丙烷衍生物含氟胺。
