The tricks for remembering or understand things that you present makes these videos invaluable for learning organic chemistry. Like the close parable. Brilliant.

One of the topics for my quiz tomorrow is Diels-Alder rxns and this video was definitely very helpful! Thank you for all that you do!

I am going to be tutoring a college student who is young and bright and she's sure to be a success in the near future. I find your videos refreshing as I brush up on my orgo. chem. I also told her about your entire you tube collection of videos which if she studies carefully, she won't even need tutoring. Chemistry might be one of my favorite subjects, but not for others, that's for sure. I didn't want to reach out to you on messenger, (as it has been a few years since I have) because I figured you're probably too busy and that's a little on the personal side anyway. I'm the guy who was studying just to learn more, but for no other reason. I had no deadlines to meet. I Hope this message finds you doing well. Thanks again !

your memory devices are really helpful: make-break-make, the endo/enter and exo/exit, and the rest are great

Your amazing!!! Every video watch, you make chemistry so easy to under stand. Thank you

thank you, you helped me a lot :)

than k you for your help! its even more helpful than my classes !

you're the best. thank you so much for explaining these so well!

concise and very clearly explained, thank you!

Thanks for such a niche representation with tricks

thank you leah, you are a life saver

Thank you Leah! This helped me a lot.

Very usefull for jee exam

Great video, thank you so much for sharing!

The Diels Alder reaction is so satisfactory, specially when you get cyclohexenes

Great Video

Okay I see it’s straight up and down

a very useful video, thank you :))

For the part at 2:40, I thought it does not matter if it’s in or out but more so if facing the same way or different directions they are cis or trans respectively

Great video ! You should be my college professor!

So you get enantiomers when all the chiral centers on a molecule are inverted in their absolute configuration. And we can see that those two structures become diastereomeric because that methyl configuration is retained. This is how I think to explain your “challenge”. I was having a little trouble finding a simpler answer in a plane/mirror of symmetry. What do you say?

How do you choose endo/exo when the dienophile is trans

I believe all of this reactions are when the dienophile attacks from the bottom, but when it attach from the top does every thing is inverse?

mmm girl you ate this up

Excellent teachings

thank you!

Great explanation, but how about facial approaches, I always find that most Diels-Alder courses don't discuss their effect on stereochemistry despite their importance in organic synthesis involving DA reactions. How would you say the facial approach of a dienophile affects the stereochemistry and the number of theoretically possible stereoisomers?

you are the best

When the dienophile is cis, the exo and endo products are meso compound isn't it ?

Knoevenagel condensation reaction please.

Hi Leah, in the beginning of the video you quickly run by some of the previous videos. However, in 0:12 , there is an example shown where the dienophile has 3 oxygens attached, one in the middle, and the other two attached on either sides via a double bond. I tried looking for this example in the two previous videos but can't locate it, so I was wondering if you made another video that includes this problem.
