通过氢化物转移至亚胺离子来氧化2,3-和2,5-二氢-1 H -1-苯并ze庚因:3 H -1-苯并ze庚因的合成
摘要:
通过将包括氢化物2转移到由杂环烯胺和BF 3生成的亚胺离子的氢化物2-2,3,5-二氢-1 H -1-苯并ze庚因的脱氢反应制备了一些3 H -1-苯并ze庚因。与2,5-二氢ħ -1-苯并吖庚因的5初步形成ħ观察-1-苯并吖庚因,在BF的存在下,其处理3导致3 ħ -1-苯并吖庚因。可以使用t-BuOK执行相同的重排。使用氘标记的底物证明了氢化物转移。叔二氢-1-苯并ze庚因也被氧化,但经过重排后变成萘胺衍生物。
Electrochemical oxidation of 2,5-dihydro-1h-1-benzazepines : Synthesis of 5H-1-benzazepines
摘要:
Formation of 5H-1-benzazepines was observed after electrochemical oxidation of the title compounds in a flow cell at a graphite felt anode and in acetic buffer. In basic medium, coupling reaction also occurs leading to [2,5-dihydro-1H-1-benzazepin-1-yl]-5H-1-benzazepines. Oxidation mechanisms are discussed.
