3. (30 points) The following transformations cannot be completed in a single step. Provide a sequence of reactions to perform each transformation, showing the reagents and structures of all isolated synthetic intermediates. The synthesis must use the given starting materials, you may also use any other starting materials with 3 or fewer carbon atoms. You may use any reagents Do not show mechanisms or the structures of reactive intermediates Shorter, more efficient syntheses are preferred, overly long or inefficient sequences will lose some credit
