Regio- and Diastereoselective Intermolecular [2+2] Cycloadditions Photocatalyzed by Quantum Dots

preprint
submitted on 13.02.2019 and posted on 14.02.2019 by Yishu Jiang, Chen Wang, Cameron Rogers, Mohamad S. Kodaimati, Emily Weiss
Here we show that colloidal quantum dots serve as visible-light chromophores, photocatalysts, and resuable scaffolds for homo- and hetero-intermolecular [2+2] photocycloadditions of 4-vinylbenzoic acid derivatives, with >90% tunable regioselectivity and up to 98% diastereoselectivity for the previously minor syn-cyclobutane products, including the syn-heda-to-tail cyclobutane, which has never been produced as the major product of a photochemical reaction.
