Methylpentynol (Methylparafynol, Dormison, Atemorin, Oblivon) is a tertiary hexanol with hypnotic/sedative and anticonvulsant effects. It was discovered by Bayer in 1913[1] and was used shortly thereafter for the treatment of insomnia, but its use was quickly phased out in response to newer drugs with far more favorable safety profiles.[2][3][4][5]
The drug was marketed again in the United States, Europe and elsewhere from 1956 well into the 1960s as a rapid-acting sedative; it was overshadowed at that point by benzodiazepines and the continued popularity of non-barbiturate sedatives such as meprobamate. [6]
Synthesis[edit]
Methylpentynol is prepared by reaction of butanone with sodium acetylide.
