Abstract: Talasterone A (1), an unprecedented 6/6/5 tricyclic 13(14 → 8)abeo-8,14-seco-ergostane steroid, together with two known congeners dankasterone B (2) and (14β,22E)-9,14-dihydroxyergosta-4,7,22-triene-3,6-dione (3), were characterized from Talaromyces adpressus. The structure of 1 with absolute configuration was elucidated based… read more here.
