With a view to elucidating the stereochemistry of quqqultetrols, components of saponified Commiphora mukul resin, D-lyxo-, L-ribo-, and L-xylo-octadecane-1,2,3,4-tetrols have been synthesised by two different routes. One method starts with D-glyceraldehyde, while the second route is based on the appropriate pentose. The absolute configuration of the natural product guggultetrol-18, has been deduced
