5. For the following molecule: a) perform a thorough retrosynthetic analysis, including Evans-Lapworth charge affinity analysis, for the target (and any intermediate target(s) you generate as part of your analysis) to guide your bond disconnections (28 points), and b) from your retrosynthetic analysis, propose a synthetic scheme from any reagents of three carbons or less. You can also use any reagents larger than these limits as long as only the specified number of carbons, or less, become incorporated from those...
