Results Synthesis. Choline surfactant 5 (16-OH) was converted to its triflate derivative with triflic anhydride in CHzCIz/pyridine. Self-phase-transfer catalytic conversion" of the triflate to 6 (1 6-SAc, X= OTf) was achieved'by stirring the CH2C12 SO-lution with excess aqueous sodium thioacetate. Ion exchange of 6 to its water-soluble chloride form, followed by deprotection with deoxygenated 3 N aqueous HCI, lyophilization, and recrystallization ...
