Reaction Steps

A mixture of (E), (Z)-4-(1-tridecenyl)-2-trimethylsilylfuran (2.0 g, 6.25 mmol) and 10% palladium or carbon (20 mg) in ethyl ether (10 ml) was hydrogenated at room temperature for 7 h. The mixture was filtered through celite and the filtrate upon evaporation gave essentially pure 4-tridecyl-2-trimethylsilylfuran. The silylfuran was redissolved in tetrahydrofuran (8 ml) and was exposed to singlet oxygen, in the presence of Rose Bengal (5 mg), for 2 h at 0°. The residue, after solvent removal, was purified by a silica column using 60% ethyl ether/hexane to give the titled furanone.
