Design a synthesis(no mechanism) for (Hint: use either a malonic ester or acetoacetic ester synthesis) Show...
6. Using either malonic ester synthesis or acetoacetic ester synthesis, outline a reaction scheme in each case to show how you will synthesize compounds A and B below. [Show all steps with structure of all intermediates and necessary reagents). A. 3-butyl-2-tetradecanone B. 2-propylpentadecanoic acid
Prepare any THREE of the following molecules, incorporating either an acetoacetic ester synthesis or a malonic ester synthesis in each synthesis. Show the reagents for each step and the product of each step. Do not draw any mechanisms. CO2Me H2N A B C D

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...
Why is acetoacetic ester more acidic than malonic ester?
28- The following molecules can be formed by either: Michael Reaction; Enamine Acylation; Acetoacetic Ester Synthesis; Michael Addition; Malonic Ester Synthesis; Robinson Annulation; Aldol Condensation; Claisen Condensation; Intramolecular Aldol Condensation; Dieckmann Condensation or a Combination of two of the above listed reaction. In each case write the proper of the reaction on the line and dissect the product into appropriate starting material. In some cases there might only be one starting material. You may use any one of the above...
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
provide the steps for the synthesis of tryptophan from phtalimido malonic ester and the detailed mechanism (written, COMPLETE explanation of the mechanism)
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
