3. Provide a reaction sequence to bring about the conversions shown below. Neither can be done in one step (treatment with just one reagent set). Both can be brought about in just two steps (treatment with two reagents or reagent sets, with work-up if needed as well). Show how you'd try to bring about the conversions required. You can use more than two steps if needed, and you c a n get partial credit if you can propose an appropriate precursor to the product even if you're not sure how to get there. Remember - NO mechanisms are needed, just reagents needed to effect the transformation
