通过GC/MS对肉桂酸的11个衍生化合物在电子轰击离子化(EI)模式下的分析,发现当此类化合物2位有氨基或羟基时,其可以历经形成质子桥配合物,发生一种类似八元环的过渡态氢重排反应,或者历经通过亲核加成反应,从而解离脱去中性分子水或醇后,形成具有喹啉酮或苯并-α-吡喃酮结构的碎片离子,该离子会进一步裂解脱去一氧化碳,具有明显的特征。 Analysis of eleven derivatives of cinnamic acid in electron impact ionization (EI) mode by GC / MS showed that when such compounds have amino or hydroxyl groups at the 2-position, they can undergo proton-bridged complex formation to form a Similar to the eight-membered ring transitional hydrogen rearrangement reaction, or after through the nucleophilic addition reaction, so as to dissociate off neutral molecular water or alcohol, the formation of a quinolinone or benzo-α-pyrone structure Fragments of ions, the ions will further crack off the carbon monoxide, with obvious characteristics.
