含有4-氧代哌啶片段的二苯并氮杂-14-冠-4与醋酐的乙酰化反应结果决定于N原子上的取代基。NH-基体先在哌啶的N原子上经过乙酰化反应,接着经过烯醇化作用和O-乙酰化反应。N-甲
The acetylation reaction of dibenzazepin-14-crown-4 containing 4-oxopiperidine fragment with acetic anhydride is dependent on the substituent on the N atom. The NH-substrate undergoes an acetylation reaction first on the N atom of piperidine, followed by enolization and O-acetylation. N-methyl
