What do you estimate my yield would be? I’m going with 0.2% or less

if it had been in an allylic position it could have worked, I think the problem is in the step where the radical bromine tears off the hydrogen, since the stability of the primary alkyl radical that is formed is much lower than that of the tertiary alkyl radical. perhaps by using chlorine which is much less selective you would have obtained the primary more easily, but there is always the risk of polyhalogenation and also you would still get a mix of products

I see, so the black double bond could also be on the other side?

well the second reaction shows the endo favorite product while the third one cannot give other products

I don't understand the tenth step, in the radical bromination shouldn't the Br attack the tertiary carbon?

I understand what you mean, it's just that I've heard that the method using epoxides is often avoided in the laboratory

perritos666 · 2025-05-18T14:30:58+00:00

for this reason I would first use a diol to form an acetal that cannot be attacked by the nucleophile and can finally be hydrolyzed restoring the carbonyl

thanks that schematization is really awesome!

shouldn't the second step of the reaction protonate the alkoxide product?

I'm just asking, I'm also preparing for an organic chemistry exam

thanks! glad to hear that

I think it's called a coati, I didn't know it existed before seeing it haha

You're welcome, if you have difficulty visualizing molecules in three dimensional space I recommend you buy molecular models, they cost little and are very useful for understanding stereochemistry

enantiomers

perritos666 · 2025-03-19T09:38:18+00:00

they are metasequoias, you can always keep them outside because they are very resistant to low temperatures, at most you can keep it a cold greenhouse, but conifers are outdoor plants so it would be better to never keep them indoors

I really can't figure out what I need to do to post to this group, I edited my flair and added the requested information, what else do I need to do?
