Question

Complete the reaction scheme. Complete structures are required; if a reagent has a common abbreviation, then the abbreviation can be used but must be completely correct. Sequential steps should be numbered. Include stereochemistry as appropriate. 13. The Colorado potato beetle is a worldwide pest. A male-produced aggression pheromone was identified and proved practical in pest management and organic farming. Complete the reaction scheme as requested in the pheromone synthesis. 13a. Provide the reagent(s). 13b. Provide the reagent(s). OH 8 5 1) CHLI 2) NHACI 13c. Predict the product. No stereochemistry needs to be shown 13d. What is the expected stereochemical outcome for the product in 13c? a single chiral compound a racemic mixture circle one: a pair of 2 diastereomers a mixture of 3 or more stereoisomers 6 8 13e. Provide the reagent(s). OH OH Oxidation OH OH OH aggression phermone

Answer 1
