The nucleophilic addition of two alkoxymethyllithium derivatives to three D-glyceraldchyde derived nitrones has been investigated. The diastereofacial selectivity of the reaction could be controlled by the appropriate use of Lewis acids as precomplexing agents of the nitrones. The obtained syn and anti adducts were further converted into C-4 building blocks and beta-hydroxy-alpha-aminoacids. (C) 2002 Elsevier Science Ltd. All rights reserved.
