The phosphorylation of alcohols by means of N-[2-(dihydrogen phosphoroxy)-5-nitrobenzyl]pyridinium hydroxide (3), which was prepared from 2-(chloromethyl)-4-nitrophenyl phosphorodichloridate (1) through two steps, was demonstrated. Alcohol with a tertiary amino group in its alkyl moiety was readily phosphorylated with 3 to afford the aminoalkyl dihydrogen phosphate in good yield. On the other hand,
证明了由 2-(氯甲基)-4-硝基苯基二氯化磷酸酯 (1) 分两步制备的 N-[2-(二氢磷氧基)-5-硝基苄基]氢氧化吡啶鎓 (3) 对醇进行磷酸化. 烷基部分带有叔氨基的醇很容易用 3 磷酸化,以良好的产率得到氨基烷基磷酸二氢盐。另一方面,通常中性醇的磷酸化仅在强碱如三乙胺存在下进行,得到相应的磷酸二氢烷基酯 (9)。因此,制备了几种磷酸二氢烷基酯9。在该磷酸化中,还观察到烷基 2-羟基-5-硝基苄基醚 (10) 的形成。
