This study describes our recent efforts to find an efficient and scalable route to tetrahydro-4H-pyran-4-one using the commercially available starting materials. The route scouting work and the full development of an efficient access to the target are described. This work culminated in the preparation of above 20 kg of the title compound in our pilot plant facility.

γ-Pyrone (1) is readily accessible in 59% overall yield via 1,1,5,5-tetraethoxy-3-pentanone (10b) and subsequent acidic hydrolysis. The synthesis enables an easy scale up, as demonstrated for intermediate 10b.

1,1-Diethoxy-3-trimethylsilyloxy-3-butene was synthesized by the action of a mixture of trimethylchlorosilane, sodium iodide, and triethylamine on 1,1-diethoxy-3-butanone.Its condensation with orthoformic ester and acetaldehyde, butyraldehyde, and isovaleraldehyde acetals in the presence of zinc chloride as catalyst was investigated.The synthesis of 1,1,5,5-tetraethoxy-3-butanone and a series of 1,1,5-triethoxy-3-alkanones was realized.

Reaction of a number of ketones with diethoxycarbenium fluoroborate in the presence of N,N-diisopropylethylamine at low temperature in methylene chloride results in a preparatively useful conversion to α-(diethoxymethyl) ketones.The method is compatible with arene, nitrile, chloride, and ester functional groups.With unsymmetrically substituted ketones, it is regioselective for the less substituted α-position.In favorable cases α,α'-dialkylation occurs.Conjugated ketones react normally at the saturated position adjacent to the carbonyl group.The mechanism of the reaction is considered.
