Investigation of the fungus Aspergillus tubingensis (ATCC 76608, Trichocomaceae) has led to the isolation and identification of two new indole diterpenes, dihydrotubingensin A (1) and dihydrotubingensin B (2). Compounds 1 and 2 were isolated from the methyl ethyl ketone (MEK) extract of A. tubingensis along with two previously reported metabolites, tubingensins A (3)1 and B (4).2 As a class, these fungal metabolites hold considerable interest due to the rare dihydrocarbazole unit. In fact, this is the first known report that describes the isolation of a dihydrocarbazole from a living system.3 The occurrence of 1-4 in the extract of A. tubingensis suggests that the dihydro compounds 1 and 2 may represent the incipient state of these metabolites, while tubingensins A and B are the nonnatural oxidation products. Details of the isolation and structure elucidation of 1 and 2 are reported herein.
