Abstract: Selective oxidation of oligoethylene glycol ether methyl 12(13)–hydroxy-13(12)-[11-hydroxy-3,6,9-trioxa-undecyl-1-oxy]-octadec-9-enoate 3 has been studied using pyridinium chlorochromate (PCC). The reaction has resulted in the formation of methyl 12(13)–oxo-13(12)-[11-hydroxy-3,6,9-trioxa-undecyl-1-oxy]-octadec-9-enoate 5 as an unexpected product wherein only the secondary hydroxyl group has been oxidized while the primary hydroxyl group has remained intact.
