The [2,3]-Wittig rearrangement of trimethylsilylpropargyl ethers of furanoidglycals derived from D-mannose and L-gulonic γ-lactone affords cis 2,5-disubstituted dihydrofurans with predominant erythro selectivity. Under the same conditions, [1,2]-Wittig rearrangement is observed with a glycal derived from D-ribonic γ-lactone.
