The first stereoselective total synthesis of (-)-3beta, 4alpha-dihydroxy-beta-dihydroagarofuran (1) and 3alpha,4alpha-axidoagarofuran (2) has been described. The key step is the epoxidation of alpha-agarofuran (6) with dimethyldioxirane.

synthetic program aimed at accessing an assortment of guaianolides, particularly those from the plant family Apiaceae as well as Asteraceae, members of which possess distinct chemical substructures and necessitate deviating synthetic platforms. An initial route employing the linear monoterpene linalool generated a lower oxidation state guaianolide, but was not compatible with the majority of family members
