Question 2 (12 marks) Design a synthesis which uses the starting material indicated to synthesize the product in the scheme below. You may use any reactions we have learned in 2220 so far, and any reactions from 2210. There is no maximum or minimum numbers of steps, though you should strive for 'conciseness' in your synthetic route. You should note the relative stereochemistry of any substituents and take that into account when designing your synthesis. For each reaction, be sure...
