实验步骤: A reactor equipped with a stirrer, reflux-condenser, thermometer and nitrogen gas inlet pipe was charged with 297 g of 7-tridecanone, 166 g of glycerol and a solvent amount of toluene, and after addition of p-toluenesulfonic acid as a catalyst, the dehydrative condensation reaction was carried out at the reflux temperature for 24 hours. The resulting crude product was washed with an aqueous solution of potassium carbonate and further with 3 portions of distilled water and finally purified by distillation under reduced pressure to provide 2,2-dihexyl-4-hydroxymethyl-1,3-dioxolane.

实验步骤: In a 250 mL round bottom flask, 5.00 g (25.5 mmol) dihexylketone, 19.7 g (255 mmol) ammonium acetate, and 1.10 g (17.8 mmol) sodium cyanoborohydride (NaBH3CN) were dissolved in 75 mL absolute MeOH and stirred at room temperature for 48 hours, until no significant amount of the starting material could be detected by NMR. The mixture was quenched by adding concentrated hydrochloric acid (HCl) dropwise (˜3 mL), then concentrated in vacuo. The resulting white solid was taken up in 500 mL water, basified to pH 10 with solid potassium hydroxide (KOH), and extracted with chloroform (CHCl3) twice (200 mL each). The CHCl3 fractions were combined and concentrated to give 4.12 g (81%) of 1-hexylheptylamine 1 as a pale yellow oil. 1H NMR (D2O, 500 MHz): δ 0.73 (t, 6H), 1.15-1.23 (m, 16H), 1.55 (m, 4H), 3.13 (m, 1H). The mixture was quenched by adding concentrated hydrochloric acid (HCl) dropwise (˜3 mL) concentrated in vacuo extracted with chloroform (CHCl3) twice (200 mL each) concentrated
