Ketene S,S-Acetals as 1,3-Dipolarophiles: Application to the Synthesis of Polyhydroxylated Pyrrolidines

Two approaches to the synthesis of the hydroxylated pyrrolidines 3 and 4, based on exploiting the reactivity of a ketene S,S-acetal as a 1,3-dipolarophile, are described.Both routes utilize a carbohydrate starting material and the strategy based on D-eryt
