Regioselective C- or O-alkylation of alkyl 4-hydroxy-2-methylthiophene-3-carboxylates with a-halo ketones is possible, depending on the solvent nature. A convenient preparative method of C-alkylation was proposed and previously not easily accessible beta-hydroxythiophene derivatives were synthesized.
