标题 :System for multiple simultaneous synthesis
发明人：DEWITT SHEILA H H; KIELY JOHN S; PAVIA MICHAEL R; SCHROEDER MEL C; STANKOVIC CHARLES J
权利人:WARNER LAMBERT CO
摘要:A system for the multiple, simultaneous synthesis of compounds preferably uses a reaction apparatus comprising a reservoir rack having a plurality of reaction wells, a plurality of reaction tubes, usually gas dispersion tubes, having filters on their lower ends, a holder block, having a plurality of apertures, and a manifold, which has ports to allow introduction/maintenance of a controlled environment. The manifold top wall has a plurality of apertures in axial alignment with the reaction tubes and a gasket which allows penetration by a needle in order to dispense and aspirate materials from the reaction tubes. Sealing members, such as gaskets, are placed between the holder block, manifold and reservoir rack and the components are releasably fastened together. A robotic sample processor is used to automate the synthesis process using the reaction apparatus.

摘要:An apparatus for multiple, simultaneous synthesis of compounds which consists of: a reservoir block having a plurality of wells; a plurality of reaction tubes, usually gas dispersion tubes, having filters on their lower ends; a holder block, having a plurality of apertures; and a manifold, which may have ports to allow introduction/maintenance of a controlled environment. The manifold top wall has apertures and a detachable plate with identical apertures. The apparatus is constructed from materials which will accommodate heating, cooling, agitation, or corrosive reagents. Gaskets are placed between the components. Rods or clamps are provided for fastening the components together. Apparatus operation involves placing the filters on the lower ends of the reaction tubes in the reservoir block wells, and the upper ends passing through the holder block apertures and into the manifold.

摘要:An apparatus and method which provides a suitable location for multiple, simultaneous synthesis of compounds. The apparatus consists of: a reservoir block having a plurality of wells; a plurality of reaction tubes, usually gas dispersion tubes, having filters on their lower ends; a holder block, having a plurality of apertures; and a manifold, which may have ports to allow introduction/maintenance of a controlled environment. The manifold top wall has apertures and a detachable plate with identical apertures. The apparatus is constructed from materials which will accommodate heating, cooling, agitation, or corrosive reagents. Gaskets are placed between the components. Rods or clamps are provided for fastening the components together. Apparatus operation involves placing the filters on the lower ends of the reaction tubes in the reservoir block wells, and the upper ends passing through the holder block apertures and into the manifold. The apparatus provides in excess of 1 mg of each product with structural knowledge and control over each compound. The apparatus can be adapted to manual, semiautomatic or fully automatic performance. Using the apparatus a series of building blocks are covalently attached to a solid support. These building blocks are then modified by covalently adding additional different building blocks or chemically modifying some existing functionality until the penultimate structure is achieved. This is then cleaved from the solid support by another chemical reaction into the solution within the well yielding an array of newly synthesized individual compounds, which after postreaction modification, if necessary, are suitable for testing for activity.

标题 :Synthesis of sulfilimines
发明人：GETMAN DANIEL P
权利人:MONSANTO CO
摘要:Processes are disclosed for preparation of N-aryl-S,S-dihydrocarbylsulfilimines by reaction of phenylisocyanate compounds with hydrocarbyl sulfoxides. The sulfilimines can be rearranged to ortho-thioalkylene anilines and the reactions can be employed in a route for converting nitrobenzene compounds to ortho-thioalkylene anilines, which are useful intermediates for preparation of herbicidal compounds.
