Abstract

Four new compounds related to azaphilones, designated falconensins A (1), B (2), C (3), and D (4), were isolated from the mycelium of Emericella falconensis, a new ascomycetous fungus isolated from Venezuelan soil. The structures of falconensins A to D (1-4) were confirmed by spectroscopic investigation and chemical correlations. These falconensins are the hydrogenated azaphilones.
