Title: Trying to understand compound UIPAC name
Post by: Maliztri on October 09, 2021, 06:23:04 PM

Hi guys

For an organic synthesis class I have to do a synthesis of 7-Methoxytetrazolo[1,5-a]quinoline-4-carboxaldehyde. To be honest I don't remember at all how to name heterocyclic compounds. I don't get the tetrazolo[1,5-a]quinoline part and why does 4-carboaldehyde is at position 4 if the methoxy group is at position 7.
I attached a screenshot of the compound that I drew on chemdraw.

Help this poor soul, please :c
Thanks!

Position 1 is one of the nitrogens in tetrazole ring. Then you orient it in a way that most atoms are located in top-right quadrant and start from there going right

Great! The "5a" really messes things up.
