Abstract
This short review highlights the hitherto realised synthetic approaches towards organic
1,2-chlorohydrins by functionalisation of alkenes (i.e., 1,2-chlorohydroxylation),
which is the most prominent access route to this class of compounds. Also, some other
synthetic approaches involving the reduction of α-chloroketones, the epoxide opening
ring by chloride anions and the utilisation of Grignard reagents for the synthesis
of these compounds and chlorination of allylic alcohols are highlighted. Finally,
enzymatic reactions for the formation of chlorohydrins are briefly summarised followed
by a short view on natural products containing this moiety.
