Versuchsvorschrift

3-(1-Hydroxytridecyl)-2-triethylsilylfuran is reacted with phenyl isocyanate and copper (2) chloride in dimethylformamide to give 3-(1-phenylcarbamoyloxytridecyl)-2-triethylsilylfuran. Oxidizing the latter intermediate with singlet oxygen and thereafter reduction with sodium borohydride gives 3-(1-phenylcarbamoyloxytridecyl)-2(5H)-furanone. Substituting phenyl isocyanate with diethyl chlorophosphate, gives 3-(1-diethylphosphonooxytridecyl)-2(5H)-furanone. Substituting phenyl isocyanate with ethyl chloroformate, gives 3-(1 -ethoxycarbonyloxytridecyl)-2(5H)-furanone. Substituting phenyl isocyanate with methoxyethyl chloromethyl ether, gives 3-[1-(2-methoxy)ethoxymethoxy]tridecyl-2(5H)-furanone.
