3,4-Dimethoxy-4′-methylbiphenyl

Analogs of amphetamine. 6. 2,5-Dimethoxy-4-methyl- and 2,5-dimethoxy-alpha,4-dimethylphenylalanines.

1 - Fluoro - 2 , 5 - dimethoxy - 4 - nitrobenzene

1-Fluoro-2,5-dimethoxy-4-nitrobenzene was synthesized in 90% yield by the reaction of commercial 2-fluoro-1,4-dimethoxybenzene with nitric acid. The structure was confirmed by X-ray crystallography. The new title compound was characterized by 1H and 13C-NMR, elemental analysis, EI-MS and FT-IR.

[2,7-Dimethoxy-8-(4-methylbenzoyl)-1-naphthyl](4-methylphenyl)methanone

In the title compound, C(28)H(24)O(4), the two 4-methyl-benzoyl groups at the 1- and 8-positions of the naphthalene ring system are aligned almost anti-parallel, the dihedral angle between the two phenyl rings being 9.64 (7)°. The dihedral angles between the two phenyl rings and the naphthalene ring system are 71.82 (6) and 71.58 (6)°. In the crystal, inter-molecular C-H⋯O inter-actions between...

4-17.2 Tronto (34-51)

Are social movements responsible for their unfi nished agendas? Feminist successes in opening the professions to women paved the way for the emergence of the upper middle-class two-career household. These households sometimes hire domestic servants to accomplish their child care work. If, as I shall argue, this practice is unjust and furthers social inequality, then it poses a moral problem for...

(6,7-Dimethoxy-4-methylisoquinolinyl)-(4'-methoxyphenyl)-methanone, a new benzylisoquinoline alkaloid from Beilschmiedia brevipes.

The leaves of Beilschmiedia brevipes provided a new benzylisoquinoline alkaloid: (6,7-dimethoxy-4-methylisoquinolinyl)-(4'-methoxyphenyl)-methanone (1) and O,O-dimethylannocherin A (2), a new natural compound which has been synthesized before. Complete 1H- and 13C-NMR data of both compounds were reported. The structures were established through various spectroscopic methods notably 1D- and 2D-N...
