2-Chloro-3-nitro-5-(trifluoromethyl)benzoic acid and -benzamide: structural characterization of two precursors for antitubercular benzothiazinones

open access: yesActa Crystallographica Section E: Crystallographic Communications, 2021
8-Nitro-1,3-benzothiazin-4-ones are a promising class of new antitubercular agents, two candidates of which, namely BTZ043 and PBTZ169 (INN: macozinone), have reached clinical trials.

N-(4-Methoxy-3-nitrophenyl)acetamide

open access: yesIUCrData, 2023
The title compound, C9H10N2O4, crystallizes with a disordered nitro group in twinned crystals. Both the methoxy group and the acetamide groups are nearly coplanar with the phenyl ring, and the C—N—C—O torsion angle [0.2 (4)°] is also insignificantly ...

Domino reaction of 3-nitro-2-(trifluoromethyl)-2H-chromenes with 2-(1-phenylalkylidene)malononitriles: Synthesis of functionalized 6-(trifluoromethyl)-6H-dibenzo[b,d]pyrans and a rare case of [1,5] sigmatropic shift of the nitro group [PDF]

open access: yes, 2013
A variety of functionalized 6-(trifluoromethyl)-6H-dibenzo[b,d]pyrans were easily synthesized in good yields under mild conditions by a domino reaction of 3-nitro-2-(trifluoromethyl)-2H-chromenes with 2-(1-phenylethylidene)- and 2-(1-phenylpropylidene ...
