De Rosa, Margherita published the artcileA three-step and enantioselective synthesis of (-)-(S)- or (+)-(R)-2-(furan-3-yl)-3,6-dihydro-2H-pyrans, HPLC of Formula: 99438-28-5, the publication is Tetrahedron Letters (2000), 41(10), 1593-1596, database is CAplus.
Enantiomerically enriched (3-furyl)-2-pyran derivatives, e.g. I, key-intermediates in the synthesis of the pharmacophoric pyranofuranone system of the bioactive natural products manoalide and cacospongionolide B, are easily accessible by a rapid sequence involving a chiral allylation and a ring closing metathesis reaction.
