Some synthetic 1-azabenzanthrones (7H-dibenzo[de,h]quinolin-7-ones) are weakly to moderately cytotoxic, suggesting that they might also show antiparasitic activity. We have now tested a small collection of these compounds in vitro against a chloroquine-re

On treatment with sodium methoxide-dimethyl sulphoxide (NaOMe-DMSO) 1-(5-halogeno-2-thienyl)-6,7-dimethoxy-2-methyl-1,2,3,4-tetrahydroisoquinolines suffer loss of halogen and are converted into the related 1-hydroxytetrahydroisoquinolines.The reaction fails with comparable 1-bromophenyl- and 1-(halogeno-3-thienyl)tetrahydroisoquinolines.A similar transformation takes place with (5-halogeno-2-thienyl)phenylmethoxymethanes, leading to the dimethyl acetal of the 5-dehalogenated-2-thienyl phenyl ketone. α-Halogenated-2 and 3-thienyl-3,4-dihydroisoquinolines undergo dehalogenation-aromatisation with NaOMe-DMSO.Mechanisms for these conversions are proposed.
