Cyclopropane was introduced into clinical use by the American anaesthetist Ralph Waters who used a closed system with carbon dioxide absorption to conserve this then-costly agent. Cyclopropane is a relatively potent, non-irritating and sweet smelling agent with a minimum alveolar concentration of 17.5% [9] and a blood/gas partition coefficient ...
Cyclopropane derivatives are numerous. [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. [5] The pyrethroids are the basis of many insecticides. [6] Several cyclopropane fatty acids are known.

In organic chemistry, cyclopropanation refers to any chemical process which generates cyclopropane ((CH 2) 3) rings.It is an important process in modern chemistry as many useful compounds bear this motif; for example pyrethroid insecticides and a number of quinolone antibiotics (ciprofloxacin, sparfloxacin, etc.).
Cyclopropane is the smallest alicyclic compound. In organic chemistry, an alicyclic compound contains one or more all-carbon rings which may be either saturated or unsaturated, but do not have aromatic character. [1] Alicyclic compounds may have one or more aliphatic side chains attached.
The small cycloalkanes – in particular, cyclopropane – have a lower stability due to Baeyer strain and ring strain. They react similarly to alkenes, though they do not react in electrophilic addition, but in nucleophilic aliphatic substitution. These reactions are ring-opening reactions or ring-cleavage reactions of alkyl cycloalkanes.
It is a hydrocarbon which, as the name suggests, is derived from the addition of a methylene (=CH 2) substituent to a cyclopropane ring. It is a colourless, easily condensed gas that is used as a reagent in organic synthesis .
