The disastereoselectivity in the nucleophilic epoxidation of gamma-hydroxy alpha,beta-unsaturated compounds using lithium-tert-butylperoxide is highly dependent on the reaction solvent but not influenced by the temperature. The free hydroxyl is key for stereoselection. (C) 2004 Elsevier Ltd. All rights reserved.
