IUPAC Naming
« on: December 30, 2023, 04:47:11 AM »
Hello,

I'm having trouble finding the correct IUPAC name for the molecule attached.
I can't find many helpful things online but my best guess is 2-(1-oxomethan-1-propylamine)-3-phenylaldehyde

Any help would be appreciated.

What about 2-Formyl- 3-phenyl- propanoic acid 1-propylamide or

3-Oxo-2-benzyl-propanoic acid -1-propylamide

I've tried downloading it but I don't think my computer supports that software, would there be another similar option?

For me the priority group here is the amide and it’s N substituted with a propyl group so it’s an N- propylpropanamide. Then you need to add in the formyl and phenyl groups, which I think are pretty straightforward at positions 2 and 3. However I am far from an expert in the complexities of IUPAC nomenclature and I’ve not been able to find this compound yet on the internet for confirmation. Perhaps one of the organic chemists on here might be happy to chip in.

As far as I am aware ACDLabs is the only one.

If I remember well at some point even IUPAC linked to the ACDLabs web page for naming rules (no idea how it is now), so I am ready to assume they are about as close to the sure reference as possible.

It's been a few days and I'm a bit surprised no one's commented further to settle this question: so I reckon it's 2-benzyl-3-oxo-N-propylpropanamide. But when I Googled this I could not find an authoritative confirmation which is a bit disappointing. Still think it's right though but happy to be corrected.
