Stereoselective Protonation of Carbanions, 3. - 1,3-Dioxolan-4-ones and 1,3-Oxazolidine-4-ones: Syntheses and Diastereoselective Protonation of their Anions

Dioxolonanones 3 and oxazolidinones 4 are synthesized by different methods together with the silyl enol ether 3aSi.The configuration of their diastereomers is determined by (1)H-NMR spectroscopy and relative retention times (vpc), backed by a c
A new highly diastereoselective synthesis of 2,5-disubstituted-1,3-dioxolan-4-ones from α-hydroxyacids

Reaction of α-hydroxyacids with acetals under weak acid catalysis gave the corresponding dioxolanones with a better diastereomeric ratio than the usual strong acid catalyzed synthesis from aldehydes.
