Four synthetic transformations (1 to 4) are shown here. Each of these has been carried out by a sequence of reactions, one of which involves a molecular rearrangement. A list of seven possible procedures is given to the right of the equations. Your job is to pick the sequence (or single reaction) that best achieves the selected synthesis. Your choices should be made by clicking an appropriate button.
