Mechanism for this reaction

What solvent/conditions are you using?

That is deffo your final product?

The attack from the lone pair on the N to the C of C=O would end up making an imine!

So, what were you given? the nitrodiketone start point and the heterocyclic product?

yes

You need to transform the carbonyls into something which is a good leaving group.

i was thinking of H2O+ groups but i don't know if to just presume there will be water or H+ in solvent

Or just do reductive amination. Your choice.

For an SN2 I wouldn't add protons, as the amino group would be protonated and make the amine lone pair a pretty bad nucleophile. What R-OX groups do you know that are good leaving groups?

Does the reaction have to be stereoselective?

i dont think i can, i just have to do the mechanism for the reaction they listed

I think so, but i dont need to explain the steroselectivity. I cant think of any leaving groups you could make with no conditions giving...

What exactly have they given you? You can't just write a mechanism if you don't know the reagents.



Never heard of a tosylate?

Okay. What will H₂ / Pd / C do to a carbonyl?

Hydrogenation of imine / iminimum intermediates. This will also explain relative stereochemistry.

reduce to alcohol?

i havent made a imine intermediate ... i dont know how to get there
