Stereoselective synthesis of styryl lactone, (+)-7-epi-goniofufurone was achieved in high yield via simple transformations from tartaric acid. The key step involves the successive stereoselective reduction of ketones with borohydride and selectride.

gamma-Oxo-butyramides derived from tartaric acid serve as excellent precursors for the synthesis of gamma-alkyl (aryl)-alpha,beta-dihydroxy-gamma-butyrolactones and for the synthesis of tetrols containing three contiguous stereogenic centres. The methodology presented here is general for the synthesis of gamma-alkyl (aryl)-alpha,beta-dihydroxy-gamma-butyrolactones. Utility of the chiral building block was demonstrated by the synthesis of naturally occurring lipid guggultetrol. (c) 2006 Elsevier Ltd. All rights reserved.
