amide of dimethylhydrazine for opening and cleavage of a [1,4]-dioxan-2-one is also described. This procedure unmasks the hydroxy dione 36 by jettisoning the chiral directing group. Regioselective O-carbamylation of the 1,3-dione 36 enables the transformation of the remaining carbonyl into the alpha-hydroxy carboxylicacid found in 2. The total synthesis of (+)-rishirilide B (2) requires 15 pots from
