A new and efficient three-step synthesis of 4H-cyclopenta[2,1-b:3,4-b′]dithiophen-4-one (CDT) (1) is described. This was achieved by a one-pot, regiospecific synthesis of bis(2-iodo-3-thienyl)methanol (13), its subsequent oxidation to the bls(2-iodo-3-thienyl) ketone (14) which after Ullmann coupling yielded the title compound 1.
