- Retrosynthesis, reduction (oc-35)The following structures are given: how can the substances be produced from the corresponding hydrocarbon plants? write down the corresponding (stable) intermediate stages. Some of these must be reduced (or oxidized) at the right place, but these technical difficulties should not be taken into account at this point.
Note also that the notation was made with a retrosynthesis arrow.{a) } /\/`|O|\OH⇒ /\/`|O|\H⇒ /\/`|OH⇒ /\/{b) } \<|>/`|O|\H{c) } \/<`|>\|O`|/OH{d) } /<`|>\/<`|O|>\/{e) } OH|_(A75);/#2\Started by:

- Functional groups react with each other, condensation reactions 2 (oc-41)[translation unavailable] at each exercise the following masses before:
– draw the required molecules with the functional groups
– let the two molecules drawn react with each other
– In addition to the product water, a new functional group is created. Which one?
– each partial task should at least three times dissolved are
Note: the molecules are to be neutral- Two identical alcohols react with each other
- Two Different Alcohols React to Each Other
- An alcohol reacts with a carboxylic acid
- Two identical carbonic acids react with each other
- Two different carbohydrates react with each other
- An amine reacts with an carboxylic acid

- Functional groups react with each other, condensation reactions 3 (oc-42)Es be following products of condensation reaction given. Draw the skeletal shapes of the corresponding reactants analogously to the first example. Note that the notation was made with a retrosynthesis arrow. Go ahead by analogy.{a1) } /\/O\/\

- What is the molecular formula
- Draw the molecule based on the molecular formula. What is noticed?
- What would the expected NMR of the (both!) structures look like?
