Get started for freeTreatment of a 1,3-diketone such as 2,4-pentanedione with base does not give an aldol condensation product. Explain.
Show how you might use an enamine reaction to prepare each of the following compounds:
Which of the following compounds are aldol condensation products? What is the aldehyde or ketone precursor of each?
(a) 2-Hydroxy-2-methylpentanal (b) 5-Ethyl-4-methyl-4-hepten-3-one
Which of the following compounds can probably be prepared by a mixed aldol reaction? Show the reactants you would use in each case.
Ethyl dimethyl acetoacetate reacts instantly at room temperature when treated with ethoxide ion to yield two products, ethyl acetate, and ethyl 2-methyl propanoate. Propose a mechanism for this cleavage reaction.
