Application of the Oxo Reaction to a 3,4-Ene

When 3-deoxy-l,2 5,6-di-0-isopropylidene-a-D-erythro-hex-3-en-ose (63) was allowed to react with carbon monoxide and hydrogen in the presence of preformed dicobalt octacarbonyl, the reaction

Acetylation of the mixture of products from the oxo reaction on the 3-acetate of (65) afforded a mixture of compounds that was shown, by gas — liquid chromatography, to consist of three main components in about 90% yield. Further work is in progress on the determination of the structure of the remaining components.
