标题 :Process for synthesis of organic compounds using magnetic particles
发明人：SUCHOLEIKI IRVING
权利人:SOLID PHASE SCIENCES CORP
摘要:This invention provides a process for the synthesis of a defined chemical entity, i.e., any desired chemical compound, in high yield using a solid support comprising a magnetic particle, in organic solvents. In general, a sequence of chemical synthetic steps are required to prepare the defined chemical entity bound to the particle. The particle comprises a resin bearing a high concentration of substituent pendant functional groups, to which the first reagent employed in the synthetic sequence binds; in subsequent reaction steps further reagents react with the growing chemical intermediate bound to the pendant functional groups until the defined chemical entity is obtained. The particle also comprises smaller paramagnetic or superpara-magnetic particles incorporated within the resin. The magnetic particle therefore responds to imposed magnetic field gradients, permitting ease of manipulation in steps involving removal of organic solvent.

摘要:A solid phase synthetic method for preparing arylretinamides is provided. The method comprises reacting hexachloroacetone with a solvent-suspended resin-bound triphenylphosphine to provide a suspension comprising an activated chlorinating reagent; reacting retinoic acid with the activated chlorinating reagent to provide retinoyl chloride; adding pyridine and a select arylamine to the resulting mixture; and stirring the resulting mixture for a time and at a temperature sufficient for the select arylamine to react with the retinoyl chloride and provide the arylretinamide. Also provided, are select arylretinamides that can be prepared by the present method, and methods of using such arylretinamides to induce apoptosis in cancer cells.

摘要:The present invention is directed to a method for producing a cyclic diamine compound (3) or a salt thereof through the following scheme: n n(wherein Ar represents a phenyl group, a pyridyl group, or a pyrimidinyl group, any of which may have a substituent; X represents NH, S, or O; ring A represents a benzene ring or a pyridine ring, which may have a substituent; 1 represents an integer of 1 or 2; m represents an integer of 1 or 2; and n represents an integer of 1 to 6). The method enables synthesis of a cyclic diamine compound (3) or a salt thereof, which serves as an ACAT inhibitor, in an industrially useful manner.

摘要:The present invention is on polymers derivatized with an organic deposition-enhancing group for their enhanced deposition onto keratin fibers, especially human hair. The deposition-enhancing group is a di-hydroxyl phenolic compound with a spacer alkyl group bound to a reactive amine or carboxyl group, which reacts with one of the hydroxyl, carboxyl, primary and secondary amine groups on the polymeric backbone. The invention is on the method of synthesizing such compounds and compositions comprising the compounds.
