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。
The conventional anticholinergic drugs for administration through inhalation have been considered to have the possibility of aggravating dysuria associated with prostatic hyperplasia mediated by blood, and it has been demanded that the conventional anticholinergic drugs for administration through inhalation will have to show reduced side effects or adverse ractions.
The present invention relates to a compound represented by the general formula (I):
(wherein A represents;
and R1, R2, R3 and R1 each a hydrogen atom or a substituent;
R5 is a substituent; X- is an anion;the symbol:
denotes an exo-form or endo-form, or their mixture), its salt or solvation product thereof. They are useful as a prophylactic and/or therapeutic agent with reduced side effects or adverse reactions for the diseases mediated by the muscarinic receptor.
