4,4'-Dichloro-3,3'-diquinolinyl sulfide 1 reacted with aryl-, heteroaryl- and alkylamines in MEDG or phenol to Ii-substituted thiazino[2,3-c;6,5-c']diquinolines 2. Reaction with ammonia, ammonium carbonate or benzylamine led to unsubstituted thiazine 2a. Alkylation of thiazine 2a with alkyl halides gave 14-alkyl-I,4-thiazinodiquinolines 2b, 2c and 2f. The nature of the 14-substituent has a significant effect on H-1 NMR and MS spectral properties.
