Participants

Reaction Steps

Jones' reagent (2.25 ml) was added dropwise to a solution of 7-(3,5,6-trimethyl-1,4-benzoquinon-2-yl)-7-phenyl-2-heptyne-1-ol (1.01 g, 3.0 mmole) in acetone (15 ml) at room temperature over the 15-minutes period. The mixture was stirred at room temperature for another 30 minutes and the acetone was distilled off under reduced pressure. Isopropyl ether and water were added to the residue, and extraction was effected. The isopropyl ether layer was separated out, washed with aqueous sodium chloride solution, dried (magnesium sulfate) and evaporated. The residue was recrystallized from isopropyl ether to give 7-(3,5,6-trimethyl-1,4-benzoquinon-2-yl)-7-phenyl-2-heptynoic acid (0.71 g, 68%).
