5. Devise a multi-step synthesis that will provide the product shown from the given starting material. (Challenging!) 6 Multiple Steps 3. When diastereomers I and I undergo an E2 elimination on treatment with sodium ethoxide in ethanol, one of the isomers react 500 times faster than the other one. Also, one isomer gives only A as a product and the other isomer gives a mixture of A and B as products. Determine the products of each isomer and explain your...
