Chemical compound
Salicyl alcohol (saligenin ) is an organic compound with the formula C6 HOH(CH2 OH . 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]
C6 H5 OH + CH2 O → C6 H4 OH(CH2 OH
Air oxidation of salicyl alcohol gives salicylaldehyde .
C6 H4 OH(CH2 OH + O → C6 H4 OH(CHO) +H2 O
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 .
