Five new naturally occurring anthracene derivatives, 1,4,10-trimethoxyanthracene-2-carbaldehyde (1), (1,4,10-trimethoxy-2-anthracen-2-yl)methanol (2), 1,4,8,10-tetramethoxyanthracene-2-carbaldehyde (3), 1,4,10-trimethoxyanthracene-2-carboxylic acid (4), a
Process for aromatic bromination
-
, (2008/06/13)
A novel procedure for bromination of aromatic moieties utilizes N-bromosuccinimide or dibromodimethylhydantoin in an aqueous alkali medium. The bromination procedure is employed for the preparation of an intermediate used in the preparation of remoxipride, an antipsychotic compound.

, p. 931 - 934 (2007/10/02)
A new bromination method employing NBS or dibromodimethylhydantoin in aqueous base is described for the synthesis of 3-bromo-2,6-dimethoxybenzoic acid (1) and other monobrominated alkoxybenzoic acids.
Chromatographic Separation of Enantiomers and Barriers to Enantiomerization of Axially Chiral Aromatic Carboxamides
Cuyegkeng, Maria Assunta,Mannschreck, Albrecht
, p. 803 - 810 (2007/10/02)
The enantiomers (M) and (P) of a series of similar aromatic carboxamides have been, for the first time, investigated analytically and enriched preparatively by liquid chromatography on triacetylcellulose.Enantiomeric purities (7-99percent), specific rotations, and barriers to rotation about the C(sp2)-C(sp2) bond (87 - 120 kJ/mol, Table 5) were determined.These energies are discussed in terms of the size of ortho substituents and of the buttressing effects by meta substituents.
Potential Neuroleptic Agents. 2,6-Dialkoxybenzamide Derivatives with Potent Dopamine Receptor Blocking Activities
Florvall, Lennart,Oegren, Sven-Ove
, p. 1280 - 1286 (2007/10/02)
A series of some novel N-(1-ethyl-2-pyrrolidinylmethyl)benzamides was synthesized and tested for dopamine receptor blockade in vivo by the ability to block the apomorphine syndrome in the rat.Several compounds were considerably more potent than sulpiride as dopamine receptor blockers and displayed low liability to induce extrapyramidal side effects (catalepsy) in the rat.The blockade of dopamine receptor activity in vivo was mainly confined to the levorotatory isomers having the S absolute configuration.The structure-activity relationships are discussed.
