The dioxepinoindole ring found in marcfortine A (1) is unique among natural products. In order to determine the importance of the substitution pattern of the C24-C25 olefin, we synthesized a variety of analogs at these positions. With the exception o

The paraherquamides and marcfortines represent a novel class of anthelmintics. The sole structural difference between paraherquamide A and marcfortine A occurs in ring G. We synthesized paraherquamide B from marcfortine A in six steps. Paraherquamide
