The generation of C-glycosides through the enolate Claisen rearrangement
Tóm tắt
The [3,3]-sigmatropic rearrangements of silyl ketene acetals obtained from aliphatic esters of furanoid and pyranoid glycals is described. The heterocyclic γ,δ-unsaturated carboxylic acids II are produced in good yields. A new preparation of furanoid and pyranoid glycals is described.
