title: Structure and biosynthesis of lecanopyrone, a naphtho[1,8-cd]pyran-3-one derivative from cultured lichen mycobionts of Lecanora leprosa.
abstract: From the cultures of spore-derived mycobionts of the lichen Lecanora leprosa a novel naphtho[1,8-cd]pyran-3-one derivative, lecanopyrone, was isolated. Its structure was determined by spectroscopic methods. The assembly pattern of acetate units in its biosynthesis was verified using sodium [1-13C]-acetate and sodium [1,2-13C2]-acetate.
