General description

tert-Butyl acetoacetate (t-BAA) is a cheap and easy to store commercial reagent. Reaction demonstrated that the more hindered tert-butyl acetoacetate (t-BAA, la) is ca.15-20-fold more reactive than the more commonly used methyl or ethyl analogs. It is widely employed as an acetoacetylating reagent.

Application

tert-Butyl acetoacetate may be used in the synthesis of:
  • various acetoacetic acid derivatives
  • acetoacetates
  • acetoacetamides
  • 1-(diethylamino)-2-acetoacetoxypropane
  • (S)-tert-butyl 3-hydroxybutyrate
  • benzothiazole β-keto ester derivatives
  • 3,4-disubstituted pyrroles
