A convergent asymmetric synthesis of gamma-butenolides

Primary tabs

Renard, Marie Eve [UCL] Ghosez, Léon [UCL]

Addition of aldehydes to the new enantiomerically pure lithiated sulfoxide 4 yielded gamma-butenolides of high enantiomeric purities after elimination of phenylsulfinic acid. The reaction with ketones was less stereoselective. (C) 1999 Published by Elsevier Science Ltd. All rights reserved.
