Catalytic cyclocarbonylation reactions using a glyceraldehyde derivative as a carbonyl source are described. The rhodium(I)-catalyzed reaction of enynes with glyceraldehyde acetonide gave bicyclic cyclopentenones as the products. This presents an interesting use of a sugar alcohol derived carbon resource as well as a convenient procedure for the cyclocarbonylation of enynes. rhodium - cyclocarbonylation
