Reaction of pyrimidyl esters of some phosphorus acids with isomeric butyl alcohols

A series of pyrimidyl esters of some phosphorus acids was prepared with the purpose of investigation of their reaction with isomeric butyl alcohols. According to31P NMR data, the obtained phosphates all are capable of phosphorylating isomeric butyl alcohols. The reactions with diphenyl (4-oxo-3,4-dihydro-2-pyrimidyl) phosphate and diphenyl (2-pyrimidyl) phosphate occur in quantitative yield under mild conditions, and the reactions with diphenyl (4,6-dimethyl-2-pyrimidyl) phosphate and dibutyl (4,6-dimethyl-2-pyrimidyl) phosphate require severe conditions to occur. In the latter two cases, certain reaction selectivity was observed, depending on the nature of the solvent and some other factors. Pyrimidyl esters of sulfur-containing phosphorus acids do not react with isomeric butyl alcohols under the studied conditions.
