Novel syntheses of thiophene fused tricyclic systems 1 and 2 are reported. The methods use intermediates 4-ethoxy-3-thiopheneamine, 4-ethoxy-3-thiophenecarbonyl aside and 4-ethoxy-3-thiophenecarbonyl chloride to effect selective, high yield syntheses of the target compounds in two steps. These methods allow preparation of thiophenesystems without substitution at the normally reactive C-1 and C-3 positions
