Tetrahydrofuran → HCID 15735700, compound

Participants

Reaction Steps

To a 0.5M solution of 9-borabicyclo[3.3.1]nonane in tetrahydrofuran (253 ml) was added dropwise, under nitrogen, a solution of 41.8 g of 4-benzyloxy-13-phenyl-1-tridecene in 100 ml of dry tetrahydrofuran. The mixture was stirred at room temperature for 3 hours, quenched by the sequential addition of 72 ml of ethanol, 24 ml of 6N solution of sodium hydroxide, and 48 ml of a 30% solution of hydrogen peroxide. The mixture was heated at 50° for 2.5 hours. Upon standing at room temperature overnight, the mixture separated into aqueous and organic layers. The organic layer was washed with 100 ml of a 10% aqueous solution of sodium sulfite and 100 ml of a saturated aqueous solution of sodium chloride, dried over anhydrous potassium carbonate and concentrated. The concentrate was taken up in 20% diethyl ether/hexane, filtered and concentrated to an oil. The oil was purified by high pressure liquid chromatography using as an eluent hexane/diethyl ether (2:1 by volume) to give 32.7 g (75%) 4-benzyloxy-13-phenyl-tridecan-1-ol as an oil.
