substituent. For the methyl, ethyl and n-propyl derivatives exclusively 6-adducts are found. Adduct formation takes place at C-6 and C-4, when the 1-substituent is an i-propyl or t-butyl group. The adduct ratio for the latter compounds is determined by the size of the substituent. 1-Aryl derivatives exhibit amination at C-2 and C-6 and the adduct ratios are dependent on the temperature. When the aryl substituent
1-烷基-3-氨基甲酰基吡啶鎓氯化物在液氨中的动画生成位置取决于1-烷基取代基的身份。对于甲基,乙基和正丙基衍生物,仅发现6-加合物。当1-取代基是异丙基或叔丁基时,加合物的形成在C-6和C-4处进行。后一种化合物的加合物比率由取代基的大小决定。1-芳基衍生物在C-2和C-6处发生胺化,加合物比率取决于温度。当芳基取代基是2,4,6-三甲基苯基时,也检测到4-加合物。比较了这些化合物被兔肝醛氧化酶氧化的位点与液氨中的共价胺化方式。
