1. The problem statement, all variables and given/known data is treated first with Li and then with CuI. The product reacts with chlorocyclopentane 2. Relevant equations 3. The attempt at a solution I don't know where to start exactly... it doesn't seem to be anything I've learned so far (substitution, addition ,elimination). All I can think of is a Corey-House synthesis, dunno if I'm headed in the right direction ?
