Herein, the stereostructure of the aromatic heptaene macrolide (AHM) antifungal antibiotic candicidin A3 (syn. ascosin A3, levorin A3) has been established upon the 2D NMR studies, consisting of DQF-COSY, TOCSY, ROESY, HSQC and HMBC experiments, as well as upon extensive molecular dynamics simulations. The geometry of the heptaenic chromophore was defined as: (22E, 24E, 26Z, 28Z, 30E, 32E, 34E). The previously unreported absolute configuration of the chiral centres of candicidin A3 was established as: (3R,9 R, 11 S, 13 S, 15 R, 17 S, 18 R, 19 S, 21 R, 36 S, 37 R, 38 S, 40 S, 41 S).
