Chiral bicyclic α,β-unsaturated lactones (6a,b and 8a,b) were easily synthesized from chiral cyclic diols (2-4) and cyclic β-keto esters (1a,b).Alkylation of 8b proceeded in a highly diastereoselective manner to afford a quaternary carbon.
Asymmetric Alkylation Using Chiral Cyclic Diols to Prepare a Quaternary Carbon
Kato, Keisuke,Suemune, Hiroshi,Sakai, Kiyoshi
, p. 3315 - 3326 (2007/10/02)
Asymmetric alkylation of cyclic and acyclic β-keto ester acetals (4, 5, 13, 14, and 18) with C2-symmetric cycloalkane-1,2-dioxy moiety proceeded in a highly diastereoselective manner to afford enol ethers (9-12, 15-17, 19a-c) with a chiral quat
