General description
2-Bromo-3-methyl-2-butene is a vinylic bromide compound. Palladium/di-1-adamantyl-n-butylphosphine-catalyzed reductive carbonylation of 2-bromo-3-methyl-2-butene has been reported. Cross-coupling reaction of 2-bromo-3-methyl-2-butene with potassium 6-(benzoyloxy)hexyltrifluoroborate and 3-(benzoyloxy)propyltrifluoroborate has been investigated.
Application
2-Bromo-3-methyl-2-butene may be used in the preparation of:
- 2,3,4,5-tetramethyl-2,4-hexadiene
- 2-iodo-3-methyl-2-butene
- diastereomers of 2-amino-3-hydroxy-4,5-dimethylhexanoic acid
- lithium reagent, 2-lithio-3-methylbut-2-ene
- D-allo-(2R,3R,4R)-2-amino-3-hydroxy-4,5-dimethylhexanoic acid-containing peptide, pipecolidepsin A.
