설명

일반 설명

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.
