Notes:
Alkylation of 2-oxo-4-thioxo-1,2,3,4-tetrahydro-benzo[f]isoquinoline 2 gave at first the S-alkyl derivatives, then the S- and O-dialkyl derivatives were formed. Compound 2 and its alkyl derivatives coupled with aryldiazonium salts. The S-methyl derivatives of 2, on acid hydrolysis, gave 1,2,3,4-tetrahydro-benzo[f]isoquinoline-2,4-dione 10, which coupled with diazonium salts. 10 gave a monochloro and a monobromo derivative. 10 reacted also with p-nitrosodimethylaniline and the product was hydrolysed to the triketo compound 14, which condensed with o-phenylenediamine to give the quinoxaline derivative 15.
