Abstract: The synthesis of thienothiepinofurans and thiepinodifurans is described. The displacement reaction between lithium furan-2-thiolate and 2-bromomethyl-substituted thiophenes and furans gave the expected thioether. The cyclization of thioether with polyphosphoric acid (PPA) in xylene gave thiepinone derivatives and heterocyclic thiolactones. The formation of the latter compounds can be explained in terms of a cyclization via the sulfur atom. The desulfuration with Raney nickel gave 3-furyl ketones in good yields.
