3′,5′-Dimethoxybenzoin esters are important photoremovable protecting groups which form 2-phenylbenzofuran derivatives upon photo-release. We utilized a similar concept to test a photochemical method of installing a benzofuran moiety to the conjugated bac

3',5'-Dimethoxybenzoin (DMB) is a bichromophoric system that has widespread application as a highly efficient photoremovable protecting group (PRPG) for the release of diverse functional groups. The photodeprotection of DMB phototriggers is remarkably cle

The design and multistep convergent synthesis of the novel photoactive ubiquinol-benzoin adduct 1a,b has been accomplished. Optical spectra of the steady-state photolysis reactions showed a smooth conversion from 1a,b to 5,7-dimethoxy-2-phenylbenzofuran (13) and ubiquinol-2 with an isobestic point at 258 nm. HPLC analysis of the photoproducts was also consistent with the clean formation of the desired ubiquinol-2 (3) and the expected 5,7-dimethoxy-2-phenylbenzofuran (2). Transient photolysis at 355 nm was consistent with a rapid photolysis rate that exceeded the instrument response time (> 106 s-1). Accordingly, the study of rapid electron-transfer events in ubiquinol oxidizing enzymes is now feasible. Furthermore, the synthetic methods developed herein will be of general application for the facile synthesis of a variety of photoreleasable substrates for studying rapid kinetic events in enzymatic reactions.
