Review Topics References Devise the most efficient synthesis for the carboxylic acid below using a starting material and reagents from the tables. Give your route by specifying the number of the starting material followed by the letters of the reagents you would use beginning with the first step. The answer 4th means treat t-butanol(4) with conc. HC (then treat the product with KOH in alcoholch). Starting materials OH B Reagents a Mg/ dry other KMnO/H,0 . Aqueous H,SO, at reflux...

1) Choose one molecule from the set and create an 8-step synthesis scheme using the chosen molecule as your starting material. You need to write the complete set of reagents and draw the product expected from each step. Reagents typically used together are considered one step, e.g. 1) LAH 2) H.O should be considered as one step. Your 8 steps must include at least one reaction from each of the chapters, aldehydes and ketones, carboxylic acid derivatives, alcohols. You can...
