THE SYNTHESIS OF THE DIHYDROMAHUBANOLIDES

Two epimeric, naturally occuring α-alkylidene-γ-butyrolactones have been prepared from a carbohydrate precursor, using a Wittig reaction to form an exocyclic double bond either with or without epimerisation at the centre α to the olefin, depending on the

The Total Synthesis of (-)-Litsenolides C-1 and C-2

The total synthesis of (-)-litsenolides C1 and C2 from D-glucose in 12percent overall yield is described in which the α-alkylidene double-bond is formed by a Wittig reaction of a C-2 oxocarbohydrate derivative.
