with isatin in the presence of NaOH via Pfitzinger reaction. These methods are more satisfactory in terms of the yield and simple one-pot operation. Structures of the products thus obtained were confirmed by spectral studies. A simple and facile synthesis of tetrahydroquinolino[2′,3′:8,7]cyclooct[b]indole and tetrahydroquinolino[2′,3′:8,7]cyclooct[b]indole-6-carboxylic acid starting from 1-oxo-1,2,3
