Category theorist: hold my beer.

Me: oh it’s a reaction scheme, so they start with this and end up with this. I’ll assume everything in the middle is correct and they get what I asked them.

Tbf sometimes it’s hard even for organic chemists because the authors will just put an abbreviation of a non-standard variation of the name of some named reaction over the reaction arrow and then proceed to draw the product in a completely different conformation from the starting material, leaving you trying to work out which carbon is which in the world’s most annoying game of spot-the-difference (or in many cases spot-the-similarity).
