| 31. | He and Waters experimented on the gas cyclopropane and were the first doctors to use it on human subjects.
|
| 32. | The small cycloalkanes in particular, cyclopropane have a lower stability due to Baeyer strain and ring strain.
|
| 33. | 1, 3-Dibromopropane was used in the first cyclopropane synthesis in 1881, known as the Freund reaction.
|
| 34. | In 1881 he discovered a method for synthesising cyclopropane : he treated 1, 3-dibromopropane with sodium metal.
|
| 35. | Due to conformational strain in the cyclopropane ring of the norcaradiene the equilibrium lies on the side of the cycloheptatriene.
|
| 36. | The added chlorine atom assists in the decarboxylation step and likely serves as the leaving group during cyclopropane ring formation.
|
| 37. | He also helped develop the anesthetic use for the gas cyclopropane, and he was a pioneer in therapeutic nerve blocking.
|
| 38. | The systematic name of this enzyme class is "'cycloeucalenol lyase ( cyclopropane-decyclizing ) " '.
|
| 39. | Alpha-mycolic acids comprise at least 70 % of the mycolic acids present in the organism and contain several cyclopropane rings.
|
| 40. | Some inhaled anaesthetics used for general anesthesia, such as cyclopropane and halothane, may reduce the effect of oxytocin and ergometrine.
