Salicyl alcohol (saligenin) is an organic compound with the formula C6HOH(CH2OH. It is a white solid that is used as a precursor in organic synthesis. [3]

Synthesis and applications

Salicyl alcohol is produced by the hydroxymethylation of phenol using formaldehyde: [4]

C6H5OH + CH2O → C6H4OH(CH2OH

Air oxidation of salicyl alcohol gives salicylaldehyde.

C6H4OH(CH2OH + O → C6H4OH(CHO) +H2O

Chemical sweeteners are formed by acetal formation with e.g. isovanillin (Cmp4). [5]

Salicyl alcohol appears as a pharmacophore in several notable β2-adrenoceptor agonists (e.g. salbutamol), as well as in synthetic estrone analogs, e.g. CID:22940780 or CID:154236944.

Biosynthesis

Salicyl alcohol is the precursor of salicylic acid. [6] It is formed from salicin by enzymatic hydrolysis by Salicyl-alcohol beta-D-glucosyltransferase or by acid hydrolysis.
