15.3 Retrosynthetic Analysis

• Again, you shouldn't try to make a list like this throughout the course.
• It would be difficult to do this task.
• If you make the first list, you will learn how to think in more than one step.
• You have to get used to thinking this way.
• Use the reactions in the beginning of your course to create a list on a separate sheet of paper.
• If you don't get a chance to write down all 50, that's fine, as long as you begin the process and draw at least 10 or 20 of them.

• We can start focusing on the main techniques for analyzing the problems after you have done this.
• The next section is about that.

• When it's your turn, you don't need to make a move immediately.
• You are supposed to think about it first.
• This means that you look at the problem in a different way.

• The synthesis problem is a multistep problem because we don't have a single reaction that allows us to do this transformation in just one step.
• The best way to start is to first look at the product.

• The product is a dibromide.
• To answer this question, you must have first mastered one-step synthesizer.

• If you haven't yet done this for all of the reactions that you have learned, you need to go back to the beginning of the chapter and read it again, so you can see where this is going.

• We know how to make dibromide from double bonds.
