- Microwave thermolysis VII: Selective diversity in the reduction using sodium hypophosphite under microwave irradiation
-
The selective reduction of nitro group into amine using sodium hypophosphite under microwave irradiation is described. The rapid reaction, solvent free conditions and selectivity over common functional groups like CN, OH, COOH, CONH2 and halogens are the distinct features of the procedure.

PCT No. PCT/JP97/00291 Sec. 371 Date Aug. 6, 1998 Sec. 102(e) Date Aug. 6, 1998 PCT Filed Feb. 6, 1997 PCT Pub. No. WO97/29079 PCT Pub. Date Aug. 14, 1997The compounds of the formula (I) wherein each symbol is as defined in the specification, pharmaceutically acceptable salts thereof and pharmaceutical use thereof. The Compound (I) and pharmaceutically acceptable salts thereof of the present invention selectively act on cannabinoid receptors, particularly peripheral receptors, cause less side effects on the central system, and have superior immunoregulating action, antiinflammatory action, antiallergic action and therapeutic effect on nephritis. Therefore, they are useful as cannabinoid receptor, particularly peripheral cannabinoid receptor activators and antagonists, immunoregulators, therapeutic agents for autoimmune diseases, antiinflammatory agents, antiallergic agents and therapeutic agents for nephritis.

- One step diazotization coupling process
-
A process for producing metal-free azo pigments in purely organic liquid or aqueous/organic liquid containing at most 10% of water calculated on the total weight of the suspension is described. In this one-step process, a suitable aromatic amine is diazotized without isolation of the obtained diazo compound and coupled with a coupling component. Both reactions are carried out in purely or essentially organic medium. The latter consists essentially of such amount of an organic liquid that a substantial portion either of the diazo component or of the coupling component or of both these reactants remain undissolved. Both reactants must be free from sulphonic acid groups. If the resulting azo pigment contains carboxylic acid groups, these can be subsequently converted to the corresponding amido or ester groups.
