摘要：

1,3,4,6-Tetra-2-thienylthieno[3,4-c]thiophene (1f) was synthesized from di-2-thenoylmethane after five steps. The cycloaddition reaction of 1f with N-phenylmaleimide yielded a pair of exo (major) and endo (minor) adducts 7 and 8, whose structures were assigned on the basis of the difference in the reactivity toward m-chloroperbenzoic acid. The reaction of 1f with phenyl vinyl sulfoxide, dimethyl acetylenedicarboxylate, and di-2-thenoylacetylene gave benzo[c]thiophene derivatives 13, 15, and 16, respectively.
