Propose an acetoacetic ester synthesis to generate each of thd following ketones: 3. Propose an acetoacetic ester synthesis to generate each of the following ketones:
Which of the following is true of the decarboxylation mechanism for malonic ester synthesis? A. The reaction happens to most carboxylic acids when heated B. The reaction involves a cyclic mechanism involving an enol C. The mechanism involves a radical that is stabilized by the additional ester group D. The diester compound undergoes a hydride shift to form a stable carbocation
Part A Draw the structure of the carboxylic acid obtained from the malonic ester synthesis if the alkyl halide is propyl bromide. Draw the molecule on the canvas by choosing buttons from the Tools (for bonds), Atoms, and Advanced Template toolbars. The single bond is active by default. 03 . . H: 200 mm D+\?3 Marvin JS ChemAxon

10. Select the compound that can not be made using the malonic ester synthesis: O o O OH MeO OMe OH Ph ОН A. B. Ph C. D. 11. In general both the malonic ester and acetoacetate synthesis require the addition of dilute acid in order to generate the final product. Why? A. the alkoxy cation needs to be eliminated C. the ionized cation partitions to the aqueous layer B. the stabilized enolate adds a proton in the separatory funnel...
The Malonic Acid synthesis is similar to the Acetoacetic Ester synthesis It uses diethyl malonate as the main starting material Draw the structure of diethyl malonate (malonic ester) Diethyl malonate can be hydrolyzed back to malonic acid and if heat is applied after the hydrolysis, will decarboxylate. Draw the mechanism for this transformation starting with malonic acid. Indicate the new C-C bonds in each molecule and then provide the organohalides which were used to synthesize each compound using the malonic...
owing compounds are "potential' targets for either the malonic ester or the aceto acetic ester synthesis? Circle them. For each of these, draw the structure(s) of the alkylating agents and structure(s) of the alkylating agents and indicate if the compound could be made efficiently by this method. OH
