MacMillan1* Couple-close as a synthetic paradigm has the potential to change the way that synthetic organic chemists approach cyclic scaffold construction. One class of cyclic molecules that has been increasingly sought after is semisaturated cyclic scaffolds, whose specific blend of Csp2- and Csp3- hybridized components confers distinct properties to these species. However, existing methods to construct these scaffolds are limited, often relying on arene saturation or annulations that require lengthy de novo syntheses. Herein, we describe a unified and highly modular couple-close strategy for the synthesis of semisaturated scaffolds. …
