  A Facile Preparation of N-(Isopropoxyalkyl) Amides by Generation and Trapping of N-Acyliminium Ions from Ionization-Rearrangement Reactions of N-Triflyloxy Amides

  摘要：

  A series of hydroxamic acids were converted to N-triflyloxy amides which were heated in 2-propanol to give N-(1-isopropoxyalkyl) amides in high yields. The method is simple, direct, and extremely tolerant of structural diversity both in the N-acyl group, as well as in the 1-isopropoxyalkyl group. N-Alkylation of secondary N-(1-isopropoxyalkyl) amides can be used for converting them to tertiary N-(1-isopropoxyalkyl) amides. N-Acyliminium ions of wide structural diversity can be generated easily from N-(1-isopropoxyalkyl) amides available by this methodology.

  Generation of N-acyl iminium ions from ionization-rearrangement reactions of N-triflyloxy amides

  摘要：

  N-Triflyloxy amides undergo ionization in refluxing isopropanol to give N-acyliminium ions which can be trapped by addition of allyltrimethylsilane to the reaction mixture. Alternatively they can be converted to N-(isopropoxy)alkyl amides and then back to N-acyliminium ions under a variety of conditions.

  controlled basic conditions, the N-methyl group of the same starting materials acts as a competent precursor of the methylene synthon required for the homologation. The logic is levered on the formation of an electrophilic iminium ion (via N–O heterolysis) susceptible to nucleophilic attack by the alkoxide previously expulsed. The procedure documents genuine chemocontrol and flexibility, as judged by the diversity

  由于众所周知的 C(O)-N 官能团对典型 C1 同系剂（例如类胡萝卜素、重氮甲烷、叶立德）的反应性，导致以 N为中心的片段在生成羰基化合物的过程中被挤出，因此正式的 C1 插入N-O键仍然不为人所知。在此，我们记录了N-甲基-N-乙酰胺（对多种O-取代基具有高耐受性）同系转化为N-酰基-N , O-缩醛。在受控的碱性条件下，相同起始材料的N-甲基基团充当同系化所需的亚甲基合成子的有效前体。该逻辑利用了亲电子亚胺离子（通过N-O 杂解）的形成，该离子容易受到先前排出的醇盐的亲核攻击。该程序记录了真正的化学控制和灵活性，根据酰胺和氮关键上取代基的多样性来判断。通过对 D 标记材料进行的实验验证了该机制的基本原理，这些实验明确地将亚甲基片段的起源归因于起始化合物的N-甲基。
