摘要：

The sequential lithiation mechanism for the selective deprotonation of tetra[3,4] thienylene (1) to form Li-4-1 in the present of n-BuLi in THF is investigated. The specific contralateral and ipsilateral selectivities of the lithiation sites in the different steps are explored. A series of tetra-substituted 1 are obtained, via Li-4-1 with electrophiles, in good yields.
