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
This disclosure describes novel substituted thieno[3,4-b][1,5]benzoxazepin-10 (9H)-ones and thieno[3,4-b][1,5]benzothiazepin-10(9H)-ones which are useful as intermediates for the preparation of 10-[4-(substituted)-1-piperazinyl]thieno[3,4-b][1,5]benzoxazepines and 10-[4-(substituted)-1-piperazinyl]thieno[3,4-b][1,5]benzothiazepines which possess anti-psychotic or neuroleptic activity.
