Descripción general

Diethyl (2-methylallyl)phosphonate is an organophosphorous compound.[1] It participates in the synthesis of α-aminophosphonate derivatives and azaphosphones. The analgesic/antiinflammatory properties of these derivatives were evaluated.[2]

Aplicación

Diethyl (2-methylallyl)phosphonate can be used as a reagent in the Horner-Wadsworth-Emmons reaction to form conjugated carbon–carbon double bonds.[3]
It can also be used as a reactant for:
  • Enantioselective total synthesis of 10-isocyano-4-cadinene as antifouling agent.[4]
  • Regiospecific preparation of 4-oxo-2-alkenylphosphonates (OAP) via silylation followed by Friedel-Crafts acylation and isomerization. OAP can serve as building blocks for the construction of polyethylenic chains.[5]
  • The synthesis of azaphosphone as a potent analgesic/anti-inflammatory agents.[2]

Reactant for:
  • Enantioselective synthesis of 10-isocyano-4-cadinene and its stereoisomers with antifouling activity
  • Preparation of 4-Oxo-2-alkenylphosphonates via silylation followed by regiospecific Friedel-Crafts acylation and isomerization

The first enantioselective total synthesis of 10-isocyano-4-cadinene, a marine sesquiterpene isolated from nudibranchs of the family Phyllidiidae, was achieved. The cadinene is expected to be a novel nontoxic antifouling agent. In the synthesis, an intermolecular Diels-Alder reaction and a SmI(2)-induced

Treatment of allylic and vinylic phosphonates with excess LiHMDS, followed by addition of chlorotrimethylsilane, afforded alpha- and gamma- silylated allylic phosphonate mixtures. Without separation, these mixtures underwent the Friedel-Crafts reaction and base-promoted isomerization to give 4-oxo-2-alkenylphosphonates, which can serve as
