The unexpected discovery of an eliminative deprotection and cyclodimerization cascade reaction sequence led to the preparation of a series of perhydrodibenzofuranones that bear a structural resemblance to the natural product incarviditone. One of the novel dimers was found to show significant antiproliferative activity towards a non-small-cell lung cancer cell line, and represents a useful lead compound for the discovery of more potent anti-cancer agents.

High yielding and diastereoselective conjugate addition reactions of a (−)-quinic acid derived enone have provided access to a small library of hybrid analogues of the anti-tumour naturalproducts antheminone A and COTC. The novel compounds were assessed for their antiproliferative activities towards the A549 non-small-cell lung cancer cell line revealing some useful structure-activity relationships
