Participants

Reaction Steps

To a solution of 43.79 g acetic acid 3-(4-tert-butyl-phenyl)-2-methyl-propenyl ester in 200 ml of tetrahydrofuran, a solution of 27.16 g potassium tert-butoxide in 200 ml of tetrahydrofuran was added at −78° C. After stirring at this temperature for 90 minutes, a solution of 53.00 g 4-oxo-undecanoyl chloride in 200 ml of tetrahydrofuran was added. After stirring at −78° C. for 2.5 hours, the solution was quenched with saturated sodium bicarbonate solution and diluted with ether. The organic phase was washed with saturated sodium bicarbonate solution and brine, dried and evaporated to dryness. The residue was purified by thin-film distillation and chromatography to yield 25.73 g of a yellow oil.
