2-Bromo-3-methyl-2-butene is a vinylic bromide substance. Palladium/di -1-adamantyl-n-butylphosphine-catalyzed reductive carbonylation of 2-bromo-3-methyl-2-butene has actually been reported. Cross-coupling response of 2-bromo-3-methyl-2-butene with potassium 6-(benzoyloxy)hexyltrifluoroborate as well as 3-(benzoyloxy)propyltrifluoroborate has actually been checked out.
2-Bromo-3-methyl-2-butene might be utilized in the prep work of:2,3,4,5-tetramethyl-2,4-hexadiene2-iodo-3-methyl-2-butenediastereomers of 2-amino-3-hydroxy-4,5-dimethylhexanoic acidlithium reagent, 2-lithio-3-methylbut-2-eneD-allo-(2R,3 R,4 R)-2-amino-3-hydroxy-4,5-dimethylhexanoic acid-containing peptide, pipecolidepsin A.
