摘要:
The invention relates to novel phosphane ligands of formula (Ia) and (Ib): (adamantyl)n P(alkyl)m (1a); (adamantyl)o (Alkyl)q P(alkylen') P(adamantyl)r (alkyl)s (1b), wherein adamantyl represents an adamantyl radical (IIa, IIb) bonded to the phosphorous atom in position 1 or 2. The invention also relates to the production and use of the above-mentioned ligands in the presence of transitional metal compounds of the 8th. Subgroup of PSE for catalytic reactions, particularly for the refining of halogen aromatics for producing aryl olefins, dienes, diarylene, benzoic acid and acrylic acid derivatives, aryl alkanes and also amines.
摘要:
1-(4-chlorophenyl)-4,4-dimethyl-pentane-3-one of formula (I) is prepared by the alkylation of pinacolone (3,3-dimethyl-2-butanone) with p-chlorobenzylchloride where the pinacolone is used both as a reagent and the solvent. The alkylation is done under either Phase Transfer Catalysis conditions in the presence of a base or in the presence of a strong base.
摘要:
A process for synthesis of a compound of Formula (X) wherein R 1 is an aryl group substituted with one to three substituent groups, wherein each substituent group of R 1 is independently C 1 -C 5 alkyl, aminocarbonyl, alkylaminocarbonyl, dialkylaminocarbonyl, halogen, carboxy, cyano, or trifluoromethyl, wherein each substituent group of R 1 is optionally independently substituted with one to three substituents selected from C 1 -C 3 alkyl, C 1 -C 3 alkoxy, phenyl, and alkoxyphenyl; and R 2 and R 3 are each independently C 1 -C 5 alkyl.
摘要:
This invention is directed to 4,5-dihydro -(1 H)-pyrazole (pyrazoline) derivatives as cannabinoid CB1 receptor modulators, to pharmaceutical compositions containing these compounds, to methods for the preparation of these compounds, methods for preparing novel intermediates useful for their synthesis, and methods for preparing compositions. The invention also relates to the uses of such compounds and compositions, particularly their use in administering them to patients to achieve a therapeutic effect in disorders in which CB1 receptors are involved, or that can be treated via manipulation of those receptors. The compounds have the general formula (I) wherein the symbols have the meanings given in the specification.
摘要:
The present invention provides compounds of formula (I), wherein R 1 represents 1-ethylpropyl, 1-methylethyl or 2-methylpropyl; or a physiologically functional derivative thereof; pharmaceutical compositions comprising the compounds, the use of the compounds for the manufacture of medicaments particularly for the treatment of inflammatory and/or allergic conditions, processes for the preparation of the compounds, and chemical intermediates in the processes for the manufacture of the compounds.
摘要:
Compounds of Formula (IA) and Formula (IB) wherein R 1 , R 2 , R 3 , R 4 , R 5 , and R 6 are as defined herein for Formula (IA) or Formula (IB), or a tautomer, prodrug, solvate,or salt thereof; pharmaceutical compositions containing such compounds, and methods of modulating the glucocorticoid receptor function and methods of treating disease-states or conditions mediated by the glucocorticoid receptor function or characterized by inflammatory, allergic, or proliferative processes in a patient using these compounds.
摘要:
The present invention relates to chalcone and chalcone derivatives and analogs which are useful as angiogenesis inhibitors. The present compounds, which are inexpensive to synthesize, exhibit unexpectedly good activity as angiogenesis inhibitors. The present invention also relates to the use of chalcone and its analogs as antitumor/anticancer agents and to treat a number of conditions or disease states in which angiogenesis is a factor, including angiongenic skin diseases such as psoriasis, acne, rosacea, warts, eczema, hemangiomas, lymphangiogenesis, among numerous others, as well as chronic inflammatory disease such as arthritis.
