A novel method for the preparation of mixed diesters of phosphoricacid has been investigated. It was found that mixed diesters of phosphoricacid were prepared by the reaction of alkyl 2-chloromethyl-4-nitrophenyl hydrogen phosphates with alcohols in dry pyridine. On the other hand, these diesters were also obtained from dialkyl 2-chloromethyl-4-nitrophenyl phosphates on hydrolysis under mild conditions
Synthetic Studies on Phosphorylating Reagent. I. The Phosphorylation of Alcohols by Means of<i>N</i>-[2-(Dihydrogen phosphoroxy)5-nitrobenzyl]pyridinium Hydroxide
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 dihydrogenphosphate in good yield. On the other hand,
