Synthesis of alkoxymethylene and alkoxycarbonyloxymethylene butyrolactones
McKee,Mawson,Weavers
, p. 3073 - 3079 (1994)
A previously published route to α-alkoxymethylenebutyrolactones has been shown to yield instead the corresponding carbonates. An alternative synthesis of the (E)-alkoxymethylene derivatives is described along with details of photoisomerisation to yield mixtures from which the (Z)-alkoxymethylene lactones can be obtained readily by chromatography.

The results of ozonolyses of enol ethers from 1.2- and 1.3-dicarbonyl compounds presented here strongly indicate that these reactions do not proceed via the established Criegee ozonolysis mechanism for nucleophilic C=C bonds. The quantitative one-step synthesis of phthalonic acid anhydride via ozonolysis of 2-(methoxymethyliden)-1H-inden-1.3(2H)-dione (28a) is described. Furthermore, a revision of the theory of alkene ozonolysis in the presence of tetracyanoethylene (TCNE) is proposed on the basis of a single-electron-transfer (SET) chemistry.
