Ikeda, Keiichi published the artcileRh(I)-Catalyzed cyclocarbonylation of enynes with glyceraldehyde: an available carbonyl source derived from sugar alcohols, Name: 1,4-Dioxaspiro[4.5]decane, the publication is Synlett (2012), 23(3), 393-396, database is CAplus.
Catalytic cyclocarbonylation reactions using a glyceraldehyde derivative as a carbonyl source are described. The rhodium(I)-catalyzed reaction of enynes, e.g., H2C:CHCH2OCH2CCR ( R = Ph, n-Bu, CMe3), with glyceraldehyde acetonide I gave bicyclic cyclopentenones, e.g., II, as the products. This presents an interesting use of a sugar alc. derived carbon resource as well as a convenient procedure for the cyclocarbonylation of enynes.
