Unexpected talaroenamine derivatives and an undescribed polyester from the fungus Talaromyces stipitatus ATCC10500

Chemical investigation of the fungus Talaromyces stipitatus ATCC10500 led to the isolation of four previously undescribed talaroenamines B−E. Interestingly, talaroenamine A had previously been isolated from the strain of T. stipitatus ΔtropC but never from a wild-type strain. In the course of this study, a new polyester was also identified.
