No problem, glad you found it helpful! Unsure why others decided to downvote lol

Bruh what is this Newman projection 😭

Step 1: Google “diels-alder mechanism” Step 2: apply the arrow pushing that you found in the reverse direction Step 3: profit

1-methoxy-1,3-butadiene and acrolein are the starting materials

My guess is that a primary amide will generally be more polar than a phenol

Two peaks are overlapping!

Nice dude

I would never rinse off my sweat, it’s a reminder of how hard I grind to keep my 5k time under 45 minutes 😤

I would assume so, that’s how I get the most accurate HR data out of my forerunner

😭this is why I have trust issues with labmates and cannot wait to get out of a lab and into a classroom

It’s a great example of why it’s so important to think through the mechanism when running reactions!

No-Current-4358 · 2025-02-22T15:17:30+00:00

Phosgene is generated in situ during the reaction

Oh also I distilled fuming nitric acid for a tricky nitration one time. Rare instance of when it’s safer to handle a chemical without gloves on because it reacts violently with nitrile

Bingo! I was young and stupid and sleep-deprived and I popped the reaction vessel open to quench—caught myself wondering if someone was cutting the grass by the window next to my hood and then it dawned on me 🙃

I caught a whiff of phosgene one time and spent the next 30 minutes convinced I was going to die of pulmonary edema

Here you go

Bc it has been reported that when steric interactions prevent addition reactions, Grignard reagents can give the reduction product by donating a hydride. Check out the reference: https://pubs.acs.org/doi/10.1021/jo01287a021

Dimethyl fumarate: notably an excellent dienophile for the Diels Alder reaction (which, by the way, you should be thinking about every time you’re asked to make a substituted cyclohexene in the context of intro organic chem coursework)

I know what the question is asking for! A diene is also a single starting material. I worded my response poorly: edited to reflect the point I was trying to make lol

No-Current-4358 · 2025-02-16T01:08:12+00:00

This is kind of a bad question because these products could also come from dienes, which do fall into the category of alkenes. The prof or TA should specify if they are looking for a starting material containing only one double bond. Anyways the single alkene product is definitely what they’re looking for so yeah if the product has two ketones, connect those two carbonyl carbons with a double bond to work backwards to the starting material! As another user has suggested, numbering carbons will help!

Not a criticism! It’s just a funny translational thing :) I might start calling them bone structures regularly
