WebCyclopropane (C3 H 6) is a hydrocarbon ring that was discovered in 1882; it began to be used as an anesthetic in 1933. 1 It is extremely flammable and is thus no longer used clinically. A gas at room temperature, it is caustic to the eyes but not to the skin. At concentrations greater than 40%, cyclopropane irritates the eyes and the large airways. WebIn the first approach, the introduction of an ester group α to the carbonyl on the cyclopropane gave a more than tenfold increase in reaction rate, allowing us to extend …
