摘要:Process for the synthesis of compounds of the formula in R[R*,S*] enantiomeric form, wherein each P1 is independently an hydroxy group-protecting group, and R2z is C1-4alkyl, benzyl or allyl, comprising, as a key step when R2z is R2x, the reaction of the compound of the formula in (S) enantiomeric form with a compound of the formula Mg &cir& +2 ((-)OOC-CH2-COOR2x)2 to obtain a compound of the formula in (S) enantiomeric form, and, as a key step when R2z is R2y, the reaction of a compound of the formula in (S) enantioimeric form with a compound of the formula Li(+)(-)CH2-COOR2y to obtain a compound of the formula in (S) enantiomeric form, wherein R2x is primary or secondary C1-4alkyl, benzyl or allyl, R2y is C1-4alkyl not containing an asymmetric carbon atom, and R3' is methyl or ethyl, processes for the synthesis of compounds of the formula comprising reacting a compound of the formula with the reaction product of a strong base and a compound of the formula optionally followed by, when R2z is allyl, cleavage of the allyl and P1 groups to obtain the corresponding compound of the formula wherein each R7 is methyl or ethyl, R is as defined in the specification, and each P1 independently and R2z are as defined above, and the compounds of the formula wherein R and each R7 are as defined above.

摘要:The present invention discusses a novel process for the synthesis of [R-(R*,R*)]-2-(4-fluorophenyl)-B,D-dihydroxy-5-(1-methylethyl)-3-phenyl-4-[(phenylamino)carbonyl]-1H-pyrrole-1-heptanoic acid hemi calcium salt by using 4-fluoro-α-[2-methyl-1-oxopropyl]η-oxo-N-β-diphenylbenzene butaneamide with (4R)-methyl 6-(2-aminoethyl)-2,2-dimethyl-1,3-dioxane-3-acetate. The compound so prepared is useful as inhibitors of the enzyme HMG-CoA reductase and are thus used as hypolipidemic and hypocholesterolemic agents.

标题 :Synthesis of organohaloboranes and alkoxyorganoboranes
发明人:BURKHARDT ELIZABETH R
权利人:MINE SAFETY APPLIANCES CO
摘要:A one-step process is provided for the synthesis of organohaloboranes, including diisopinocampheylchloroborane, and alkoxyorganoboranes. The present process does not utilize a thermally unstable ether adduct or a malodorous dimethyl sulfide adduct as required in prior processes. In general, the organohaloboranes are synthesized in a single reactor by reacting olefin(s) and/or alkyne(s) with boron trihalide and diborane. Alkoxyorganoboranes are synthesized in a single reactor by reacting olefin(s) and/or alkyne(s) with alkylborate and diborane.

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.
