15.1 One-Step Syntheses

15.1 One-Step Syntheses

  • The problem can only be solved by three or four steps.
  • This attitude will kill your grade as the course progresses.
    • Let's compare organic chemistry to a game of chess.
  • You are learning to play chess.
    • How they are named, how to set up the board, and so on are some of the things you learn about first.
    • You learn how each piece moves and how they capture each other.
    • There is a lot of strategy involved in your first game.
    • There are many strategies that involve thinking more than one move in advance.
    • It is necessary to know how to move the pieces.
    • You need to plan out the next few moves so that you can coordinate an attack on your opponent's pieces.
    • Imagine if you took the time to learn how to move the pieces, but then said to yourself that you weren't good at strategy.
    • You won't be good at one aspect of the game if you keep playing chess.
    • The whole game is one aspect of the game.
  • You can either learn how to play chess or not.
  • The chemistry is the same.
    • It's all about strategy.
    • You have to learn how to think a few moves ahead.
    • You don't have to tell yourself that you aren't good at synthesis because you can focus on the other aspects of organic chemistry.
  • The second half of the course is about learning reactions and applying them.
    • Everything you have learned so far has prepared you for synthesis.
  • Don't be lazy, and don't think that you can get through the course if you don't know how to propose syntheses.
    • If you do, you will find that your performance in the course will spiral down to a point that will make you very unhappy.
  • There are some techniques that will make you feel more comfortable with synthesis problems, and there are some exercises that you can do to increase your knowledge of approaching synthesis problems.
  • One-step synthesis is the first synthesis problem you will encounter.
    • Predicting products is more difficult than these problems.
    • You need to be comfortable with one-step synthesizer before you can move on to multistep synthesizer.
  • We need to make a list of reactions, but we will leave out the reagents so that we can practice filling in the reagents.
  • This list will grow as you learn more.
    • You should duplicate all of the reactions that you have recorded here.
    • The reagents need to be filled in on the photocopy.
    • When you have entered five new reactions, repeat this procedure.
  • As the course progresses, you will be in good shape to solve one-step synthesis problems if you keep up with this exercise.
    • Keeping up with the work and not waiting until the night before the exam is the hardest challenge you will face.
    • It will be very difficult to master this material if you wait.
    • Don't make that mistake.
    • The secret to success in this course is to do a little bit every night.
    • Cramming doesn't work well in organic chemistry.
  • On the next page, begin your list.
  • We can help you solve problems by going oversynthesis.
  • Don't fill in the mechanisms or the reagents.
    • The starting material and products should be drawn in front of the arrow.
    • The space above the arrow should be empty.
  • Try to fill in the reagents on the photocopied page.
  • If you want to make a reaction on this page, fill in the reagents.
  • To fill in all of the reagents, take the previous pages and duplicate them.
  • To fill in all of the reagents, take the previous pages and duplicate them.
  • To fill in all of the reagents, take the previous pages and duplicate them.
  • To fill in all of the reagents, take the previous pages and duplicate them.
  • To fill in all of the reagents, take the previous pages and duplicate them.
  • To fill in all of the reagents, take the previous pages and duplicate them.
  • To fill in all of the reagents, take the previous pages and duplicate them.
