1.8: Reactions at the α-Carbon, Part II (Summary)

  • Page ID
  • Before moving on to the next chapter, you should:

    • Be able to draw reasonable mechanisms for reactions of the following type:
      • Decarboxylation of a \(\beta\)-carboxy ketone or aldehyde
      • Claisen condensation and retro-Claisen cleavage
      • Hybrid decarboxylation-Claisen condensation
      • Conjugate addition
      • \(E1cb\) elimination
    • Understand (though not necessarily memorize) the fatty acid synthesis and degradation cycles, and how the Claisen. retro-Claisen, conjugate addition, and \(E1cb\) elimination steps fit in.
    • Be able to draw a complete mechanism for the Rubisco reaction.
