A new divergent approach to (+)-goniofufurone (1) and 7-epi-(+)-goniofufurone (2), as well as the first total synthesis of crassalactone C (3), has been achieved starting from D-xylose. In a preliminary bioassay, all three natural products 1, 2, and 3 showed remarkable in vitro antiproliferative activities against K562, Raji, and HeLa neoplastic cell lines.
