thumb|L-pac produced by biotransformation of benzaldehyde Phenylacetylcarbinol (PAC) is an organic compound that has two enantiomers, one with R- and one with S-configuration. (R)-PAC, which is commonly called -PAC, is known as a precursor in the synthesis of pharmaceuticals such as ephedrine and pseudoephedrine.

Hydroxyacetone, also known as acetol, is the organic chemical with the formula CH3C(O)CH2OH. It consists of a primary alcohol substituent on acetone. It is an α-hydroxyketone, also called a ketol, and is the simplest hydroxy ketone structure. It is a colorless, distillable liquid.

Furoin or 1,2-di(furan-2-yl)-2-hydroxyethanone is an organic compound with formula C10H8O4. It can be produced from furfural by a benzoin condensation reaction catalyzed by cyanide ions.

Flutemazepam was initially first synthesized in 1965, but was not further described until a team at Stabilimenti Chimici Farmaceutici Riuniti SpA in the mid-1970s. It is a short-acting (9–25 hr elimination half-life) fluorinated analogue of temazepam that has powerful hypnotic, sedative, amnesiac, anxiolytic, anticonvulsant and skeletal muscle relaxant properties. Flutemazepam has been shown to have similar pharmacological properties to temazepam, but with more powerful sedative-hypnotic and anxiolytic properties. It has been found to be effective for the treatment of the most severe states of

The medication is available alone or in combination with an estrogen. It is taken by mouth.

Danielone is a phytoalexin found in the papaya fruit. This compound showed high antifungal activity against Colletotrichum gloesporioides, a pathogenic fungus of papaya. A laboratory synthesis of danielone has been reported.

Hydroxynorketamine (HNK), or 6-hydroxynorketamine, is a minor metabolite of the anesthetic, dissociative, and antidepressant drug ketamine. It is formed by hydroxylation of the intermediate norketamine, another metabolite of ketamine. As of late 2019, '(2R,6R)-HNK' is in clinical trials for the treatment of depression.
