Amplification of anti-Diastereoselectivity via Curtin-Hammett Effects in Ruthenium Catalyzed Hydrohydroxyalkylation of 1,1-Disubstituted Allenes: Diastereoselective Formation of All-Carbon Quaternary Centers
Under the conditions of ruthenium catalyzed transfer hydrogenation, 1,1-disubstituted allenes 1a–1c and alcohols 2a–2g engage in redox-triggered generation of allylruthenium-aldehyde pairs to form products of hydrohydroxyalkylation 3a–3g, 4a–4g and 5a–5g with complete branched regioselectivity. By e...
