Homework 12 Fall 2009 1. Write the mechanism and the products for the following reaction (note that there will be two products in this reaction): O + O H HO 2. Write the mechanism and the product for the retro aldol reaction: O HO HO - 3. Write the mechanism and the product for the retro aldol reaction: OH CHO HO - 4. When treated with base the following compound undergoes an intramolecular aldol reaction to give a product containing a ring (78% yield) O O H HO - C 10 H 14 O 5. Propose the structure for each of the following letters: OH OH PCC A OH - B C 11 H 16 O 6. The aldol reaction is reversible. Acid hydrolysis of pulegone produces an aldol that can be then hydrolyzed to
