Abstract

Aside from the thianaphthene derivatives relatively little has been reported about other condensed ring systems of thiophene. For the preparation of some S-isosteric analogs3 of Pamaquine as antimalarials the route chosen was via 3-hydroxythieno (3, 2-b) pyridine, an isoster of S-hydroxyq~ inoline.~ The formation of this compound is intimated by Plazek and Suehardas in their synthesis of 6-thiopyrindigo (Fig. 1); however, its isolation was not ...
