Trapper Keeper (South Park)

"Trapper Keeper" is the twelfth episode of the fourth season of the animated television series South Park, and the 60th episode of the series overall. It originally aired on Comedy Central in the United States on November 15, 2000. In the episode, a man from the future wants Cartman's new Trapper Keeper, while Mr. Garrison's kindergarten class holds an election for class president with confusing results. The subplot with the class president election is a parody of the 2000 United States presidential election and the controversy surrounding its outcome.

Plot

Kyle comes to school with a Dawson's Creek Trapper Keeper. He is joined by Cartman who reveals he has a special, advanced Dawson's Creek Trapper Keeper Ultra Keeper Futura S 2000, which has incredibly advanced computerized features including a television, a music player with voice recognition, OnStar and the ability to automatically hybrid itself to any electronic peripheral device. He purchased it to make Kyle envious; around the same time, a mysterious white man going by the pseudonym Bill Cosby appears and begins to ask about Cartman's Trapper Keeper, which the man then attempts to steal. He succeeds by buying Cartman's trust, despite Cartman saying "I'm not supposed to have male friends over 30; I kinda got screwed over on that once." When "Bill Cosby" is caught by Officer Barbrady and Cartman, he explains his actions: the Trapper Keeper binder is destined to gain sentience and hybrid into a supercomputer to conquer the world in the future and wipe out all traces of humanity. Cosby himself is a cyborg from the future named BSM-471, sent back in time to destroy the binder before it could rise to power; Cosby manages to destroy it, but Cartman buys another one and refuses to allow it to be destroyed.

Acetoxy group

Acetoxy group, abbreviated AcO or OAc, is a chemical functional group of the structure CH₃-C(=O)-O-. It differs from the acetyl group CH₃-C(=O)- by the presence of one additional oxygen atom. The name acetoxy is the short form of acetyl-oxy.

Functionality

An acetoxy group may be used as a protection for an alcohol functionality in a synthetic route although the protecting group itself is called an acetyl group.

Alcohol protection

There are several options of introducing an acetoxy functionality in a molecule from an alcohol (in effect protecting the alcohol by acetylation):

Acetyl Halide, such as Acetyl chloride in the presence of a base like triethylamine

Activated ester form of acetic acid, such as a N-hydroxysuccinimide ester, although this is not advisable due to higher costs and difficulties.

Acetic anhydride in the presence of base with a catalyst such as pyridine with a bit of DMAP added.

An alcohol is not a particularly strong nucleophile and, when present, more powerful nucleophiles like amines will react with the above-mentioned reagents in preference to the alcohol.
