1-(4-Formyl-2,6-dimethoxyphenoxy)-4-chlorobut-2-yne

Abstract

A reaction of biomass-derived aldehyde synringaldehyde and half an equivalent of 1,4-dichlorobut-2-yne was attempted in order to obtain a bis-aldehyde with an alkyne spacer. The reaction was carried out in a basic media to effect bis O-alkylation, as described in literature for the preparation of structurally similar compounds. Nevertheless, only mono alkylation was observed.
