1) Illustrate the products A, B and C and outline the important enolates that are formed for dictating
the preferred stereochemistry with mechanistic insights. (Use Newman projection(s)).
5 PTS
2) How would you make each diastereomer of the product from the same alkene? 4 PTS
3) How would you attempt to transform this allylic alcohol into both diastereomers of the epoxide
stereoselectively? You are not expected to estimate the degree of success. 4 PTS
4) Here is an outline of the AstraZeneca synthesis of a thromboxane analogue. Explain the
reactions, giving mechanisms for each step, and explain how the stereochemistry is controlled.
