(12 pts) A biochemist, Dr. Tsang, has come to you to ask your assistance to synthesize two isotopically labelled methylsuccinic acids so she could probe an intriguing biosynthetic pathway. The compounds should be specifically labeled with 14C as indicated by *. Due to financial reasons, the source of the isotope is the salt Na14CN. Outline a synthesis that will accomplish this objective. Clearly indicate the reaction...
