, (2018/10/19)
The invention discloses a key intermediate of 5-oxo-tetrahydropyrane-3-carboxylate and a preparation method of the key intermediate. The preparation method of the key intermediate comprises the following steps: carrying out halogenating reaction by taking 2H-pyran-3,5(4H, 6H)-diketone (compound II) as a raw material to obtain a compound III; carrying out reduction reaction on the compound III to obtain a compound IV; carrying out halogen carbonyl insertion reaction on the compound IV to obtain a compound V; carrying out reduction on double bonds in a structure of the compound V to obtain a compound VI; and carrying out oxidation of hydroxy on the compound VI to obtain carbonyl and 5-oxo-tetrahydropyrane-3-carboxylate (compound I).
