RuO4 and NaIO4. Treatment of these diones with metal acetylenides then gives mixtures of erythro- and threo-1,5-hexadiyne-3,4-diols with good erythro-selectivity. Reaction of the erythro-diols with thiophosgene in the presence of n-BuLi or KH as base results in the formation of the corresponding cyclic thionocarbonates in moderate to good yields. Reaction of the cyclic thionocarbonates with 1,3-dimethyl-2-phenyl-1
