The stereoselective total synthesis of (−)-galantinic acid 1 and 1-deoxy-5-hydroxysphingolipids 4 is described via Prins cyclization protocol followed by reductive ring opening sequence of substituted pyrenol derivative 6. The target molecules were synthesized using a common synthetic intermediate epoxide 5. Besides, we also proposed synthetic pathways to achieve other structural analogues using common intermediates.
