S. Faizi et al., MANNICH REACTION-PRODUCT OF QUINOLIN-8-OL (OXINE) AND ITS ANTIBACTERIAL ACTIVITY, Australian Journal of Chemistry, 50(8), 1997, pp. 861-864
Quinolin-8-ol (1) on reaction with 2,6-dichloroaniline and m-nitrobenz
aldehyde afforded 7-(alpha-hydroxy-m-nitrobenzyl)quinolin-8-ol (2), wh
ich is an unusual Mannich reaction product. The structure of (2) was d
etermined by spectroscopic and single-crystal X-ray diffraction studie
s. Preliminary antimicrobial screening showed that (1) and (2) have ac
tivity against a large number of Gram-positive and Gram-negative bacte
ria.
