Process for preparing 2,4-dioxotetrahydrofuran-3-carboxylates |
| abstract |
Process for preparing 2,4-dioxotetrahydrofuran-3-carboxylates of the formula (I) and/or (I′) n ncomprising the reaction of a haloacetyl chloride compound of the formula (II)n n nwith a malonic ester of the formula (III)n n nin which Hal, R 1 and R 2 have the definitions stated in the application, in the presence of a suitable base and optionally in the presence of a solvent; the addition of a sufficient amount of water to the reaction mixture; and the isolation of the desired 2,4-dioxotetrahydrofuran-3-carboxylate. |
