The absolute configuration of natural goniofufurone is shown to be 2 by an unambiguous synthesis of its enantiomer 1 from D-glycero-D-gulo-heptono-γ-lactone involving an intramolecular Michael reaction as the key step.

(acetylation, hydrolysis, deacetylation, glycol cleavage, Wittig reaction, and hydrolysis) into the γ-lactone 5 which underwent an intramolecular Michael reaction to yield (-)-goniofufurone 1. Likewise reactions of the monoacetate 12 gave (-)-8-epi-goniofufurone 3.
