Preparation of racemic and enantiomerically pure cyclic ketene acetals was written by Diaz-Ortiz, A.;Diez-Barra, E.;de la Hoz, A.;Prieto, P.. And the article was included in Synthetic Communications in 1993.Product Details of 2568-30-1 This article mentions the following:
Cyclic ketene acetals have been prepared from α-haloaldehyde di-Me acetals by transacetalization and subsequent elimination in PTC without solvent conditions. No racemization has been observed when an enantiomerically pure diol has been used. Stability and storage conditions have been studied. Thus, cyclocondensation of XCH2CH(OR) (R = Me, X = Cl, Br) with diols gave 77-93% cyclic acetals which underwent dehydrohalogenation with KOH-Bu4N+ Br– to give cyclic ketene acetals, e.g. I–III. In the experiment, the researchers used many compounds, for example, 2-Chloromethyl-1,3-dioxolane (cas: 2568-30-1Product Details of 2568-30-1).
2-Chloromethyl-1,3-dioxolane (cas: 2568-30-1) belongs to dioxole derivatives. Dioxoles, particularly fluorinated dioxoles, are used as co-monomers to make polymers that find use in forming protective coatings for chemical resistance. Dioxole functionalized metal-organic frameworks have also been recently reported.Product Details of 2568-30-1
