Hi everyone. I know my question is probably quite irrational, but I do not know how to find the answer in other way.
So, I need to present my knowledge of organic chemistry. Because of this, I am looking for a synthesis of a compound (natural, or some kind of drug), which would include as many as it can of these reactions:
-carbonyl reactions (all these condensations (Claisen, Dieckmann), Robinson annulation, Michael additions, etc.)
-Mannich reactions,
-Diels-Alder,
-Wittig reactions,
-some kind of rearrangement - Cope, Claisen, Beckamnn,
- some kind of conjugate addition,
-generally reduction, oxidation, sub, add, and elimination reactions on the level of Year 1,2, perhaps 3 of University.
I know it probably sounds stupid, but I am still in high school and I have no clue where should I look up for such a synthesis. It doesn't have to be synthesis, done in the real life. I am just looking for compound which would provide me with many opportunities, to present my knowledge of org chem.
I would be really gratefull for some suggestions, and I am really sorry if my question does not make any sense.
Kindest Regards,
Aleksandra
