Suvn~nnary. The action of methplthioiiicthylene-triphenylphosphorane on 2,3:4,5-di-(I-isopropylidene-aldehyde-1.-arabinose Icd with good yields to t h c corresponding unsaturatcd sugar which underwent electrophilic addition with a high regiospecificity. This provides a useful ncw route for a one-carbon chain extension in the carbohydrate series.
