Enantioselective synthesis of allylboronates and allylic alcohols by copper-catalyzed 1,6-borationTools Luo, Yunfei, Roy, Iain D., Madec, Amaël G.E. and Lam, Hon Wai (2014) Enantioselective synthesis of allylboronates and allylic alcohols by copper-catalyzed 1,6-boration. Angewandte Chemie International Edition, 53 (16). pp. 4186-4190. ISSN 1433-7851 Full text not available from this repository.AbstractChiral secondary allylboronates are obtained in high enantioselectivities by the copper-catalyzed 1,6-boration of electron-deficient dienes with B2(pin)2. The reactions proceed efficiently using catalyst loadings as low as 0.0049 mol%. The allylboronates may be oxidized to the allylic alcohols, and can be used in stereoselective aldehyde allylborations. This process was applied to a concise synthesis of atorvastatin.
