Abstract
5-Bromo- and 5,5-dibromo-1,1,1-trihalo-4-methoxypent-3-en-2-ones (brominated enones) have proven to be attractive building blocks for the construction of heterocyclic and polyheterocyclic compounds bearing a trihalomethyl moiety through interesting cyclocondensation, alkylation, and cycloaddition reactions. This review compiles all of the reactions conducted with these brominated enones since they were first disclosed in 2001.
