Hydrochloric Acid → (S)-3-hex-5-enylsulfanyl-2-methyl-propionic acid

Participants

Reaction Steps

A solution of 1.62 g (10 mmol) (S)-3-acetylsulfanyl-2-methyl-propionic acid in 20 ml MeOH is treated with 7.5 ml 4N NaOH and 1.63 g (10 mmol) 6-bromo-hex-1-ene. After being stirred for 1 h at rt the mixture is diluted with 50 ml EtOAc and acidified with 25 ml 1N HCl. The organic phase is washed with brine, dried with sodium sulfate and concentrated in vacuo to yield (S)-3-hex-5-enylsulfanyl-2-methyl-propionic acid as an oil which is used without purification for the next step.
