Synthesize the following diketone. All carbons in the
product must come originally from molecules of
methanol.
Homework Answers
When Methanol is added to HI then Water gets removed and MeI is formed .
Before adding Mg, completely drying is needed and then Grignard reagent is formed.
In step-II , commercially available cyclic anhydride is made into such a molecule that we reach our min target.
Step-III, first acyl chloride is substituted as this is more electrophilic than ester and then use of LDA ensures the less substituted enolate and forms 6 member ring.

Show the most efficient synthesis of the product from the starting material. Show all reagents your need over each arrow, and draw all products and intermediates (do not combine steps). You do not need to show the mechanism for any steps. Show all molecules synthesized along the way, and pay attention to stereochemistry. If a racemic mixture is produced in any step, show both products formed. If you make a mixture of regioisomers in any of the steps, place a...
