An efficient methodology for the synthesis of thieno[2,3-c][2,7]-naphthyridine (6), thieno[2,3-c]isoquinoline (11), furo[2,3-c]isoquinoline (14), [1]benzothieno[3,2-d]thieno[2,3-b]pyridine (21), and [1]benzothieno[3,2-d]furo-[2,3-b]pyridine (26) skeletons from 4-[o-cyanoarylthio(or oxy)]butyronitriles with base via Smiles type rearrangement reaction followed by the cyclization is described.
