Two new naphthalene derivatives from an endolichenic fungal strain Scopulariopsis sp.

Abstract

Chemical investigation on an endolichenic fungal strain Scopulariopsis sp. led to the isolation of two new naphthalene derivatives, 1-(4′-hydroxy-3′,5′-dimethoxy-phenyl)-1,8-dimethoxynaphthalen-2(1H)-one (1) and 1,8-dimethoxynaphthalen-2-ol (2). Their structures were determined by spectroscopic techniques (UV, IR, MS, 1D, and 2D NMR).
