The acid-mediated transformation of syn and anti methylene interrupted cis,cis and cis,trans bisepoxides to tetrahydrofurans is high yielding, and demonstrates both regioselectivity and stereoselectivity. Trans,trans methylene interrupted bisepoxides do not yield tetrahydrofurans under the same conditions.

Chemical analysis of N. anomala collected off rock platforms along the southern coast of Australia yielded a cis-dihydroxytetrahydrofuran (2), the structure for which was assigned by spectroscopic analysis, chemical derivatization and biomimetic synthesis. Tetrahydrofurans from Notheia anomala are reported for the first time as potent and selective inhibitors of the larval development of parasitic
