What is DIETHYL (2-METHYLALLYL)PHOSPHONATE 97?

The Uses of DIETHYL (2-METHYLALLYL)PHOSPHONATE 97

Diethyl (2-methylallyl)phosphonate can be used as a reagent in the Horner-Wadsworth-Emmons reaction to form conjugated carbon–carbon double bonds.
It can also be used as a reactant for:

Enantioselective total synthesis of 10-isocyano-4-cadinene as antifouling agent.
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.
The synthesis of azaphosphone as a potent analgesic/anti-inflammatory agents.

General Description

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