Synthetic Routes to the Carcinogen IQ and Related 3H-Imidazoquinolines
Ronne, Erik,Grivas, Spiros,Olsson, Kjell
, p. 823 - 830 (2007/10/02)
2-Amino-3-methyl-3H-imidazoquinoline (IQ, 1a) and four new IQ homologues, viz. its 7-methyl, 8-methyl, 9-methyl and 7,9-dimethyl derivatives 1c-1f, have been conveniently synthesized from the appropriate 6-methoxyquinolines 3 rather than from the p
