Diethyl allylphosphonate 화학적 특성, 용도, 생산

• 화학적 성질

  clear colorless liquid

• 용도

  Reactant for:
  
  • Copolymerization of phosphonated allyl monomers and maleic anhydride
  • Enantioselective synthesis of solamin type mono-THF acetogenins
  • RCM reaction yielding oxaphospholene and oxaphosphinene heterocycles
  • Synthesis of spongistatin 2 using Wittig coupling
  • Stereoselective synthesis of pentacyclic furanosteroids
  • Preparation of protected polyhydroxylated β -amino acid constitutents of microsclerodermins

• 화학 반응

  To a stirred solution of diethyl allylphosphonate (582.5 mg, 3.0 mmol, 1.5 equiv) in dry THF (25 mL) was added NaH (60% dispersion in mineral oil, 120 mg, 3.0 mmol, 1.5 equiv) portion wise under nitrogen atmosphere at 0°C. After 15 min, aryl/alkyl aldehyde 14a–x, 14z (2.0 mmol) in dry THF was added to the reaction mixture and stirred at 0°C until the completion (monitored by TLC) of reaction. It was then quenched with saturated aq. NH4Cl and the solution was extracted with EtOAc (2×20 mL). The combined organic layers were dried (Na2SO4) and concentrated. The residue was purified by silica gel column chromatography using petroleum ether/EtOAc (9:1, common for all compounds unless specified) as eluent to afford (E)-1-aryl/alkylbutadienes 7a–x, 7z.
  The CM reaction of 2 with dimethyl vinylphosphonate (3a) and diethyl allylphosphonate (3b) under a classic thermal condition with 3 mol % of H-G II at 40 °C.
