AbstractA convergent synthesis of IMMH002 in 36% overall yield starting from bromobenzene is described with a key Suzuki–Miyaura cross-coupling reaction used to provide a crucial intermediate. The route does not require column chromatography and solves the most intractable quality problem caused by a homologue by-product in the original linear synthesis. Furthermore, reducing the use of Lewis acid mediated reactions improves the environmental impact of the synthesis and reduces overall waste. The new route described herein is more efficient, convenient, reliable, and economically more viable when compared to the previously reported linear route.

AbstractIn this paper, the synthesis of the carbon skeleton of cotylenin A aglycone is described. The key reactions, including an intramolecular aldol reaction, an aldol coupling reaction, and a ring-closing meta­thesis, allow for the effective and stereoselective access to the carbon skeleton of cotylenin A aglycone. The stereochemistry was confirmed by single-crystal X-ray crystallographic analyses of related compounds.
