文摘

Azaheterocyclic analogues of quinoloxyacetamide antimycobacterials are reported. Potent antimycobacterial scaffolds were identified. Unambiguous structure determination was carried out by 13C-NMR, HSQC/HMBC and NOE. NMR methodology can be applied generally for ambident heterocyclic nucleophiles.
