Q 10 - Synthesis question. Show how the starting material can be converted to the product through any of the reactions you have learned in Ochem-l and Ochem-Il. Show all the reagents you need and indicate the stereochemistry when appropriate. You do not need to show arrow pushing like in a mechanism question, only the reactions. If a chiral molecule is formed mark the chiral center with an asterisk (*) and write "racemic" below the structure. All carbon atoms in...
