Microwave irradiation has been used to accelerate the conversion of isatin (1), 5-chloroisatin (2), and N-benzylisatin (3) to their thiosemicarbazones and their subsequent cyclization into 1,2,4-triazino[5,6-e]indole-3-thiols 7 and 8; and the W-benzyl derivative 9. Selective and complete alkylation of 1, 7, 8, and 9 has also been achieved under microwave irradiation.
