PROCEDURE
实验过程
A reaction vessel (30 ml, a two-neck, eggplant type flask) is subjected to nitrogen gas purging and NaBH3CN (0.5 mmol, 31.4 mg), Bu2(t-Bu)SnCl (0.0125 mmol, 4.1 mg, 3.5 μl) and tert-butanol (1 ml) are added. Then, 3-iodo-1-phenylheptane (0.25 mmol, 75.5 mg, 57.5 g 1) is added to the solution. The introduction of nitrogen gas is discontinued, a nitrogen gas-filled black butyl rubber balloon is set instead, and oxygen (0.375 mmol, 9 ml) is bubbled into the solution using a syringe. The reaction mixture is then incubated on an oil bath at 60° C. After 24 hours, heating is discontinued and the reaction mixture is diluted with pure water (10 ml) and extracted with ether (15 ml×4). The residue is purified by column chromatography (silica gel 2 g, ethyl acetate/hexane 20%) to provide 1-phenyl-3-heptanol (26.9 mg, 55%). 1H NMR revealed that the crude product comprised the alcohol/reduced compound/starting compound in a molar ratio of 56/28/16.
