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.
