标题:游离质子化引起的气相逆迈克尔反应:质谱法中质子化华法林的碎片化.
摘要:进行了质子化华法林及其衍生物(化合物1至5)的质谱研究.逆迈克尔反应观测到取代的亚苄基丙酮和4-羟基香豆素的损失.添加的质子最初通过最热力学上有利的互变异构体中的氢键定位在两个羰基氧之间.碰撞激活后,添加的质子迁移到4-羟基香豆素的c-3(称为解离质子化位点),导致形成中间离子-中性络合物(inc).在inc中,进一步的质子转移产生质子结合的复合物.质子结合的复合物的一个氢键裂解产生质子化的4-羟基香豆素,而其他氢键的分离产生质子化的亚苄基丙酮.理论计算表明,1,5质子转移途径是最热力学上有利,并支持inc的存在.取代基效应和动力学方法都用于解释质子化的4-羟基香豆素和质子化的亚苄基丙酮衍生物的相对丰度.对于单取代的华法林,给电子取代基有利于质子化取代的亚苄基丙酮的反应生成,而吸电子基团有利于质子化的4-羟基香豆素的形成.取代基效应和动力学方法都用于解释质子化的4-羟基香豆素和质子化的亚苄基丙
