19-O-Acetylchaetoglobosin B and 19-O-Acetylchaetoglobosin D, Two New Metabolites of Chaetomium globosum

Article abstract of DOI:10.1002/hlca.19810640710

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