SYNTHESIS OF DISODIUM PREPHENATE

An efficient synthesis of disodium prephenate is described which illustrates the use of 5-ylidene-1,3-dioxalan-4-ones for the synthesis of acid labile α-keto acids.

Synthesis of Disodium Prephenate

An efficient synthesis of disodium prephenate has been achieved utilising a 5-ylidene-1,3-dioxolan-4-one intermediate as a protected α-keto acid.
