A practical and general one-pot synthesis of mono-N-substituted, functionalized aspartic acids has been developed. The N-substituted aspartic acids are formed directly from alkali maleates and primary amines in hot DMSO. Products from several different primary amines can be prepared chemo selectively in moderate to good yields. (c) 2005 Elsevier Ltd. All rights reserved.
