making intresting substances from already available compounds
So..i feel like it's time for me to explore organic chemistry a bit more, and i want to synthesize intresting new compounds (it has to be cool
ofcourse or els why even bother lol)
i can buy many insecticides/fungicides such as azoxystrobine and cypermethrin and the list goes on i don't remember a lot of the other compounds and i
was wondering if they're of any use as precursors to other intresting stuff ?
Anyways whatever information yall have i'd love to hear it.

This question is always troublesome when it comes up, people often expect us to name them some really awesome compound with interesting properties
that is not too challenging to make.
Sadly most of the really exciting compounds are all hellishly hard to make.
If what you want is just to dip your toes and learn some stuff about organics then i would advise first making some phenylthalein as thats very useful
in a lab and the difficulty of making it can be talored somewhat, in that you could just buy phthalamide and phenol or you could deacetylate and
decarboxylate aspirin to make phenol and oxydize ortho-zylene and heat it up to 180°c with some urea that you have isolated from your own urine to
prepare phthalamide.
There is also alot of very beutiful smelling fragrant esters and aldehydes that arn't too challenging to prepare.
https://en.m.wikipedia.org/wiki/Aroma_compound
If you complete all this and wish to go into true multistep organic synthesis then i would perhaps advise replicating nudrages total synthesis of
pyramethamine.
I have some others in my head like some vanilloid compunds and a few others but they are all too complicated or dangerous or illegal.
Ill mention a couple that peak my own interest, you atleast want to learn about them theoretically.
Sodium thiopental
https://en.m.wikipedia.org/wiki/Sodium_thiopental
Capsazepine
https://en.m.wikipedia.org/wiki/Capsazepine
Cubane
https://en.m.wikipedia.org/wiki/Cubane
Saxitoxin
https://en.m.wikipedia.org/wiki/Saxitoxin
Sufficiently advanced science is indistinguishable from madness.

hey thanks ! the esters and aldehydes are definitely intresting ,I'll take look into a few of them.
I have already made phenolphthalein using gloves following nilered's procedure but
pyramethamine is still a bit of a strech for me as with the saxitoxin and sodium thiopental but i'm gonna get there
since I had easy acess to those organic compounds I mentioned earlier i thought they'd be a better closer route to something...

I would recommend binge-watching chemplayer on bitchute. If you don't come away from that inspired and having a whole lot of ideas then... well maybe
OC is not the right direction.
At an entry level (which is where I am at), esters, aldehydes, phenol from aspirin, isolating compounds (eg by fractionating gasoline or solvent
mixes) styrene from polystyrene, grignards, extractions from -- well whatever you have available: thymol, camphor, capsasin, caffeine, theobromine,
piperine, and go from there.
UC235 has some good ideas on his channel too.

Pesticides can be useful precursors in org. chem. if you know what to look for.
Modern ones are sadly mostly useless. They are too big and complicated molecules (like your examples). The older ones were usually smaller and more
useful because their hydrolysis (other "lysis") products were more interesting.
Then comes the legislation problem: here in the EU they culled most of the "good, old ones" in an ongoing process since 2009 or so for various
reasons. If you live elsewhere then your chances may be better to find the right ones. In a developing 3rd world country - it could be a gold mine!
I planned to do an "exploiting pesticides" (mini)series on them but while I was planning they removed the best candidates from the store shelves! Even
if I had stockpiled some the series would be obsolete because no one could repeat the synths.

I think the hardest part of answering this question is determining what is cool. Usually I look at molecules and I think "does this turn into anything
cool?" and the answer is usually "no" but I'm not really looking at deep modifications because I'm trying to consider every path instead of just one
of them.
Like, pyrimethamine is cool?
You might be able to make a BIG base:
http://www.chtf.stuba.sk/~szolcsanyi/education/files/Chemia%...
You can make butanedione from MEK, isopropylamine from acetone, potassium fluoride by the rxn of K2CO3 and BaF2 (do not use glass!), acetonitrile from
ethyl acetate, trimethyl orthoformate from acetone via chloroform...

Well well well...guess what
It is a gold mine over here ! I'll take another trip to the store and write down everything that's available , I'm sure there's atleast one or two
very useful chemicals

I can get my hands on a lot of chemicals including fluorides so I don't want to risk exposure to fluorine or HF
I can also get some otherwise kinda hard to get intermediates if I wanted to build a more or less complicated molecule
And that's true cool can be many things. but anything that Q from Mi6 would freak out about meats the definition
