Full textOphiorrhine A, G and ophiorrhiside E are monoterpene indole alkaloids which were isolated from the plant Ophiorrhiza japonica and trichocarpon. We achieved the first total synthesis of ophiorrhine A, G and ophiorrhiside E. Several strategies were investigated to construct the indolopyridone moiety of ophiorrhiside E, the postulated biosynthetic precursor of ophiorrhine A. Eventually, the Friedel-Crafts-type coupling of indolyl-acetamide with secologanin-derived acid chloride delivered ophiorrhine G. Cyclodehydratation of a protected form of the latter was followed by the desired spontaneous intramolecular Diels-Alder cycloaddition of protected ophiorrhiside E leading to ophiorrhine A, which could be converted to an unnatural product with a carbazole skeleton. We have investigated the total synthesis of pestalustaine A, a sesquiterpenoid which was isolated from an endophytic fungus pestalotiopsis adusta. We performed a ring expansion of a 6-membered intermediated to form the 7-membered core, a ring closing metathesis of a diene to construct the bridged 7/7 skeleton, and an intramolecular 1,4 addition to yield the pivotal tricyclic 7/5/6 framework. Through X-ray diffraction analysis of a crystal of an intermediate with the 7/5/6 core, we discovered that our structure differs from the one proposed in the isolation publication. By analyzing the spectra of the isolated natural product, we thought that the authors might have misassigned the structure
