(42) Predict the major organic product or products of the following reactions. Indicate stereochemistry in the products where appropriate. If there is no reaction, indicate by writing N/R.
II. (20) Mechanism. Outline a reasonable and complete mechanism for the formation of the products shown. Include correct arrow notation for the movement of electrons, and be sure to show ALL the steps. Include any relevant resonance structures for the intermediate(s).
A. (10) Give a mechanism to show the transformation of the intermediate into the product. HINT: A second imine-type group is likely to form, but its aromatic tautomer is the FINAL product.
B. (10) Show how each product can be made from the resonance stabilized anion produced after step 1.
III. (20) Transform. Show the reagents necessary to accomplish the following chemical transformations. You may use any readily available and reagents. More than one step will be necessary, so show intermediate products for each step. Correct retrosynthetic analysis will receive partial credit.
A. (10) Hint: Remember there are two functional groups of differing reactivity in the starting material.
