Cyclopropanes

Cyclopropanes are a family of organic compounds containing the cyclopropyl group.

An example of the former, cyclopropyl cyanide is prepared by the reaction of 4-chlorobutyronitrile with a strong base.

[3] Substituted cyclopropanes undergo the reactions associated with the cyclopropyl ring or the substituents.

[4] Many biomolecules and pharmaceutical drugs feature the cyclopropane ring.

Famous example is aminocyclopropane carboxylic acid, which is the precursor to ethylene, a plant hormone.

(1 R ,3 R )- or (+)-trans- chrysanthemic acid .
1-Aminocyclopropane-1-carboxylic acid plays an important role in the biosynthesis of the plant hormone ethylene. [ 5 ]
