Process for producing 1,3-dioxin-4-one derivatives

A process for producing 1,3-dioxin-4-one derivatives having a lower alkyl group at 2-position and useful as a starting raw material for prostaglandins, with a high yield is provided, which process comprises reacting formyl Meldrum's acid with a lower aliphatic carbonyl compound of 2 to 4 carbon atoms in a solvent containing the carbonyl compound at 100° to 120° C., while portionwise adding the acid into the solvent, the total quantity of the acid added being 0.2 mol or less per liter of the solvent.

SYNTHESIS OF 1,3-DIOXIN-4-ONES UNSUBSTITUTED AT THE 5- AND 6-POSITIONS AND THEIR PHOTOADDITION TO ALKENES

A general synthetic method of 5,6-unsubstituted 1,3-dioxin-4-ones and their photoaddition to alkenes are described.The photoadducts thus obtained were found to give, merely by refluxing in water, alkanes having carboxaldehyde and acetic acid appendages at the vicinal position.

Synthesis of 1,3-dioxin-4-one Derivatives
