provided evidence that this one‐pot synthesis proceeds through at least twelve consecutive transformations and includes at least nine different chemical reactions, making it the longest cascade reaction sequence known to date. We describe the scope and limitations of the cascadesynthesisapproaches and the development of an enantioselectively catalyzed centrocountin synthesis.
In biology-orientedsynthesis, the scaffolds of biologically relevant compound classes inspire the synthesis of focused compoundcollections enriched in bioactivity. This criterion is, in particular, met by the scaffolds of natural products selected in evolution. The synthesis of natural product–inspired compoundcollections calls for efficient reaction sequences that preferably combine multiple individual
