The use of Grignard reagents in multi-step synthesis is widely employed. For each of the reaction sequences below, draw the major organic product that would be present after each reaction of the sequence. No mechanisms, no explanations, just draw the products (in total, 14 reaction products A to N are required). You may have to consult your lecture material and/or the textbook to solve some of these problems The use of Grignard reagents in multi-step synthesis is widely employed. For...

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...
