植烷三醇(异构体混和物)

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: One g of phytantriol (3.0 mmol, Sigma-Aldrich) was refluxed using deanstock apparatus for 15 hr in 25 ml of acetone solution with toluene sulfonic acid as catalyst. After the completion of the reaction, the acetone solvent was removed under reduced pressure and the resultant was extracted with chloroform solution. The extract was washed with saturated sodium bicarbonate solution and was again washed with saline to obtain 0.3 g of (2-(2,2-dimethyl-[1,3]dioxolan-4-yl)-6,10,14-trimethyl-pentadecan-2-ol) of which 1- and 2-positions were protected. for 15 hr After the completion of the reaction the acetone solvent was removed under reduced pressure the resultant was extracted with chloroform solution The extract was washed with saturated sodium bicarbonate solution was again washed with saline
