Description and Uses
4-Bromo-1-butyne is used as a reactant in the synthesis of:
- Macrocycles by cobalt-mediated [2+2+2] co-cyclotrimerization.
- 2,4,5-trisubstituted oxazoles by a gold-catalyzed formal [3+2] cycloaddition.
- Intramolecular 1,3-dipolar cycloaddition to synthesize 1,3,4-oxadiazoles.
- Lactones bearing alkynes for reductive cyclization in the preparation of azulene derivatives.
- Substituted α-pyrones by gold-catalyzed coupling reactions.
