The aim of the present study was the synthesis of phospholipids containing a drug molecule instead of a fatty acid. Valproic acid and ibuprofen served as model compounds. The target molecules were synthesized either starting from sn-glycero-3-phosphocholine (1) or using (S)-2-O-benzyl-1-O-tritylglycerol (11) and (R)-2-O-benzyl-1-O-tert-butyldiphenylsilylglycerol (12), respectively, as key intermediates. With respect to the surface properties and the ...
