Abstract

Two new metabolites have been isolated from cultures of Chaetomium globosum. The structures of 19‐O‐acetylchaetoglobosin B (4) and 19‐O‐acetylchaetoglobosin D (5) are assigned. The ^13^C‐NMR. spectra of chaetoglobosin A (1), 19‐O‐acetylchaetoglobosin A (2), chaetoglobosin C (3), 19‐O‐acetylchaetoglobosin B (4), 19‐O‐acetylchaetoglobosin D (5) and of cytochalasin G (6), a (3‐indolyl)‐[11]cytochalasan isolated from Pseudeurotium zonatum, have been interpreted.
