Tetrahydro-4 H-pyran-4-one: From the Laboratory Scale to Pilot Plant Manufacture

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.

SYNTHESIS OF 1,1-DIETHOXY-3-TRIMETHYLSILYLOXY-3-BUTENE AND STUDY OF ITS CONDENSATION WITH ACETALS AND ETHYL ORTHOFORMATE

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.
