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.
