(3S)-3-methylheptanoic acid

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To 10 g. of 3-(S)-methyl-1-heptanol in 175 ml. of acetone was added over 45 minutes 90 ml. of Jones reagent dropwise at 15°-20° C. After 15 minutes, 15 ml. of isopropanol was added and stirring continued for 30 minutes. The reaction was poured into water and the product extracted with ether. The extracts were combined, washed with water, a sodium bisulfite solution and a brine solution and dried over magnesium sulfate. Removal of the solvent gave 10 g. of the product as a liquid, b.p. 84°-88° C./0.4 torr, [alpha]D =-4.46 (CH3OH C=0.105 g/ml.). dropwise at 15°-20° C continued for 30 minutes the product extracted with ether washed with water a sodium bisulfite solution and a brine solution and dried over magnesium sulfate Removal of the solvent gave 10 g
