  Synthesis of organophosphates with fluorine-containing leaving groups as serine esterase inhibitors with potential for Alzheimer disease therapeutics

  摘要：

  Acetylcholinesterase and butyrylcholinesterase inhibitors are potential cognition enhancers in Alzheimer disease. O,O-Dialkylphosphate inhibitors with 1-substituted 2,2,2-trifluoroethoxy leaving groups were synthesized by phosphonate-phosphate rearrangement. Substituents in the 1-position of the leaving group along with the O-alkyl groups modulated potency and selectivity against acetylcholinesterase, butyrylcholinesterase, and carboxylesterase.

  Treatment of phosphorus pentachloride with four molar equivalents of fluoroalcohol gave symmetrical phosphates (RFO)3PO in isolated yields between 10–92% [RFCF3CH2, C2F5CH2, HCF2CF2CH2, C3F7CH2, (FCH2)2CH, (CF3)2CH, C2F5(CH3)CH]. The reaction proceeded best for fluoroalcohols having many fluorine atoms. 2,2-Difluoroethanol HCF2CH2OH and 1,3-difluoroisopropanol (FCH2)2CHOH did not react cleanly and

• The synthesis and reactions of dialkyl fluoroalkyl phosphates

  Dimethyl and diethyl fluoroalkyl phosphates were prepared from (1) a dialkyl phosphite with a fluoroalcohol, triethylamine and carbon tetrachloride, (2) a dialkyl chlorophosphate with a fluoroalcohol and triethylamine, and (3) a dialkyl chlorophosphate with the sodium salt of a fluoroalcohol. Dimethyl and diethyl (2,2,2-trifluoroethyl) phosphates reacted with bromotrimethylsilane (TMSBr) in chloroform to give two products with loss of alkyl bromide. The major product was an alkyl (trifluoroethyl) trimethylsilyl phosphate, RO(TMSO)P(O)OCH2CF3 and the minor product was a bis(trimethylsilyl) trifluoroethyl phosphate, (TMSO)(2)P(O)OCH2CF3. The mechanism presumably involves initial attack of an alkoxy oxygen atom on the silicon atom of bromotrimethylsilane. Diethyl (2,2,2-trifluoroethyl) phosphate is resistant to chlorination. It did not react with oxalyl or thionyl chloride in chloroform under prolonged reflux. Unlike triethyl phosphate, it did not react with phosphorus oxychloride in chloroform under reflux.
