G. Vidari et al., DIASTEREOSELECTIVE SYNTHESIS OF THE SAPONACEOLIDE TRICYCLIC SPIROKETAL SUBSTRUCTURE, Tetrahedron letters, 34(16), 1993, pp. 2685-2688
Starting from geraniol we prepared the tricyclic spiroketal substructu
re 5a of saponaceolide molecules. Cis- and trans- tetrahydropyran lina
lool oxides 18a and 18b were also synthesized during these studies.
