Cas no 35051-49-1 (Ethyl 2-Diethoxyphosphorylpentanoate)

Ethyl 2-Diethoxyphosphorylpentanoate is a phosphonate ester compound with applications in organic synthesis, particularly as a versatile intermediate in the preparation of α-phosphorylated carbonyl derivatives. Its structure features a pentanoate backbone with a diethoxyphosphoryl group at the α-position, enabling reactivity in Horner-Wadsworth-Emmons (HWE) olefination reactions and other carbon-carbon bond-forming processes. The ethyl ester moiety enhances solubility in organic solvents, facilitating handling in synthetic workflows. This compound is valued for its stability, predictable reactivity, and utility in constructing complex molecules, including pharmaceuticals and agrochemicals. Its phosphonate group also allows for further functionalization, making it a useful building block in medicinal and materials chemistry.
