Enzyme-catalyzed C(sp3)–H aminations for the highly enantioselective construction of chiral 2-oxazolidinones†
Abstract
As a rapidly growing field, C(sp3)–H functionalization is being used to access a wide range of important molecular targets. The enzymatic activity of C(sp3)–H is a powerful synthetic tool to develop valuable building blocks. In this study, engineered myoglobin variants were found to be capable of C(sp3)–H activation under mild conditions via mediated nitrene transfer. Using this approach, 2-oxazolidinones and γ-lactams with high enantioselectivity were obtained through intramolecular cyclization using readily available and stable N-acetoxyamides as substrates.
