Stereoselective syntheses of malyngamide X (1) and its 7'(S)-epimer are described. A Lewis acid (Et2AlCl) mediated anti-aldol reaction was employed to generate the stereocenters C-7 and C-8. The route is convergent and provides a convenient access to the synthesis of structural variants of malyngamide X. Stereochemistry at C-7' in the molecules of natural and synthetic 1, and 7'(S)-epi 1 was confirmed by NMR chiral solvation experiments. (c) 2007 Elsevier Ltd. All rights reserved.
