Chad builds upon the last lesson on DielsAlder reactions to comprehensively cover Cycloaddition Reaction in general. He starts with a review of the DielsAlder reaction and shows the difference between when it is performed under thermal vs photochemical conditions. He also shows when suprafacialsuprafacial vs suprafacialantarafacial relationships between diene and dienophile are allowed and forbidden and the resulting stereochemistry associated with each. Finally, Chad also covers examples 6 + 2 and 2 + 2 cycloadditions under both thermal and photochemical conditions.

I've created an organic chemistry page that organizes all my videos by chapter just an easier way for you to watch my YouTube videos. Check it out at https://www.chadsprep.com/chadsorgan...
