3,4‐(Hydroxymethyl‐ethylenedioxy)thiophene ( 4 ) and 3,4‐(2′‐hydroxypropylenedioxy)thiophene ( 4' ′) were synthesized from dimethyl 3,4‐dihydroxythiophene‐2,5‐dicarboxylate ( 1 ), which were isomers and difficult to separate. When they were esterified with tetrathiafulvalene carried carboxylic acid group, only 3,4‐(hydroxymethyl‐ethylenedioxy)thiophene ( 4 ) could be esterified. No such selectivity was observed when the isomers were esterified by lauric acid and benzoic acid, respectively.
