tert-Butanol → cis t-Butyl 3,7,11-trimethyldodeca-2,4-dienoate

Participants

Reaction Steps

One gram of thionyl chloride is added with stirring at room temperature to 0.5 g. of trans/cis 3,7,11-trimethyldodeca-2,4-dienoic acid and the mixture heated at about 50° for 10 minutes. Excess thionyl chloride is removed by evaporation and then t-butyl alcohol (about 2 equivalents) is added and the mixture heated at about 50° for about 5 minutes. Excess t-butyl alcohol is removed by evaporation to yield trans/cis t-butyl 3,7,11-trimethyldodeca-2,4-dienoate which is purified by chromatography.
