3. Using 2-methyloxirane and 2-bromopropane as your only sources of carbon, show how you would synthesize 4-methyl-2-pentanone. Show all reagents and conditions and synthetic intermediates, but you do not need to draw any curved arrows. D 2-methyloxirane Br i 2-bromopropane 4. The reaction of the epoxide with methoxide produces one of the two constitutional isomers of methoxy-methylcyclopentanol shown below. Write the steps in the mechanism for this process. Be sure to show the following: (1) the structure of any intermediates that are formed during the mechanism, (2), what, if anything, is added or lost during each step of the mechanism, (3) any non-zero formal charges found on the structures that you write. REMEMBER: You may not use any materials except those that are given in the equation. H₂C NaOMe/MeOH OH 4-methyl-2-pentanone -or- X -OH
