Stereoselectivetotalsynthesis of α,β-unsaturated lactone (1a), isolated from Ravensara crassifolia, has been achieved efficiently starting from chiral 2,3-O-isopropylidene-d-glyceraldehyde (3) followed by asymmetric allylation and ring-closing metathesis. The antiproliferative activities of compounds 1a, 1b and the unusual bicyclic compound 2 were evaluated against three-cancer cell lines, THP-1
