1. A C-to-O atom-swapping reaction sequence enabled by Ni-catalyzed decarbonylation of lactones

Chem. Sci. 202213, 1095-1100. DOI: 10.1039/D1SC06968C

Luu, Q. H.; Li, J.*

Advances in site-selective functionalization reactions have enabled C to O 2022single atom changes on the periphery of a complex molecule, but reaction manifolds that enable such changes on the core framework of the molecule remain sparse. Here, we disclose a strategy for carbon-to-oxygen substitution in cyclic diarylmethanes and diarylketones to yield cyclic diarylethers. Oxygen atom insertion is accomplished by methylene and Baeyer-Villiger oxidations. To remove the carbon atom in this C-to-O “atom swap” process, we developed a nickel-catalyzed decarbonylation of lactones to yield the corresponding cyclic diaryl ethers. This reaction was enabled by mechanistic studies with stoichiometric nickel(II) complexes that led to the optimization of a ligand capable of promoting a challenging C(sp2)-O reductive elimination. The nickel-catalyzed decarbonylation was applied to 6-8 membered lactones (16 examples, 32-99%). Finally, a C-to-O atom-swapping reaction sequence was accomplished on a natural product and a pharmaceutical.
