The reduction of ethyl acetoacetate with sodium borohydride is
show below. Explain why the product of the reaction does
not have two alcohol functional groups.
QH NaBH4 ethanol, 0°C
write the mechanism for the hydrolysis of ethyl acetoacetate in an acidic environment and the decarboxylation of the acetoacetic acid product.
Draw the product of ethyl acetoacetate, base, 3-bromopentane, hydrolysis and heat.
The reaction is the Pechmann reaction of resorcinol and ethyl acetoacetate to form 4-methylumbelliferone: When HCl is added to the product, protonation occurs at the carbonyl oxygen of the ester. Draw the conjugate acid of this reaction and explain why 4-methylumbelliferone is more basic than a typical ester. Note: my professor mentioned something about Lewis acids/bases and mentioned how bases are more electron rich. I would like to explain how the product is more basic than a typical ester using...

co₂Et 4. A Chem 241 student was given an experiment to synthesize compoun OH acetoacetate. The student prepared 1 mole equivalent of methylmagnesium lo which was then slowly added to a solution of ethyl acetoacetate in ether. Every 1 went well, Indeed, even without the annlication of heat the reaction mixture Dubbie orking carefully, with supervision and advice from the lab instructor, the student worked- up the reaction and isolate - LII Caction and isolated an excellent vield of...
