Chem 231, Assignment 5 page 6 of 5 Part IV - Multistep Synthesis [14 marks] A. Propose a synthesis of compound A starting from dimethyl malonate. When choosing your synthetic steps, you can use any hydrocarbon with three or fewer carbon atoms, any solvents or inorganic reagents, and any organic reagents that do not contribute carbon atoms to the carbon skeleton in the product. Clearly show the required reagents and the product of each step. You do not need to...

012- Synthesis question A-L. Show how the starting material can be converted to the product through any of the reactions you have learned in O.Chem-I and O.Chem-I1. 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 racemic mixture is formed indicate the chiral center/s with an ASTERISK( and write racemic next to the structure. All carbon atoms should come...

Draw the mechanisms that explain the formation of the two products below from the one starting material. Show all steps and arrows (6 pts) H-SO4 heat H3C он CH3 CH3 Diels-Alder reactions involve some further stereochemical considerations that we did not talk about. Mainly, these are the formation of the endo and the exo products (starting page 361 of the book). Using the example below, explain the difference between the endo and the exo products.

4) (2 pts each) Outline a synthesis (i.e., simply show the reagents/reactants for the necessary reactions) for each compound below from the designated starting material. Use reagents you've learned about in Orgo I and II. The number of arrows does not necessarily correspond to the number of steps required. As a general rule, any carbon units in the products that were not in the starting materials should come from molecules containing 7 or fewer carbons. Things that don't end up...
