标 题:Combinatorial organic synthesis of unique biologically active compounds
发明人：MCALPINE SHELLI R; TAYLOR RACHEL E; BOLLA MEGAN L; SEGALL ANCA M
摘要:The invention provides a method for making a combinatorial library of cyclic compounds, such as Holliday junction-trapping compounds, comprising the steps of (a) obtaining a plurality of trimers according to the generic structure X 1- X 2- X 3 , wherein X 1 , X 2 and X 3 can be independently any naturally or nonnaturally occurring amino acids or peptidomimetics thereof; (b) optionally coupling a spacer S to the trimer at either end; (c) cyclizing two trimers or trimer-spacer conjugates in a head-to-tail orientation; thereby obtaining a combinatorial library of compounds, wherein the library does not include an unmodifed or naturally occurring Holliday Junction-trapping compounds. The invention additionally provides methods macrocyclic compounds that are synergimycin derivatives.

标 题:Nucleophilic substitution process
发明人：STAHLY G PATRICK; STAHLY BARBARA C
权利人:ETHYL CORP
摘要:Nitroarylacetic acid esters are prepared by reacting a nitroaromatic compound which is devoid of halogen on the aromatic ring carrying a nitro group with an alpha,alpha-disubstituted acetic acid ester in an inert solvent and in the presence of a base so that the ester undergoes a nucleophilic substitution on an unsubstituted ring carbon of the nitroaromatic compound during which an alpha-substituent functions as a leaving group. Nitrobenzene acetic acids and their esters are useful intermediates for the synthesis of pharmaceuticals.

摘要:Nitroarylacetonitriles are prepared by reacting a nitroaromatic compound which is devoid of halogen on the aromatic ring carrying a nitro group with an alpha,alpha-disubstituted acetonitrile in an inert solvent and in the presence of a base so that the nitrile undergoes a nucleophilic substitution on an unsubstituted ring carbon of the nitroaromatic compound during which an alpha-substituent functions as a leaving group. Nitrobenzene acetic acids and their nitriles are useful intermediates for the synthesis of pharmaceuticals.

标题:Process for preparing pure substituted 2,5-diarylamino-terephthalates and the corresponding free acids

摘要:2,5-Diarylamino terephthalates are obtained in good yields and excellent purity when the aromatic nitro compound used for oxidizing the corresponding dihydro-2,5-diarylamino terephthalate contains the aromatic radical of said diarylamino groups, i.e. when the amine formed during the oxidation is that from which said diarylamino groups device. The products yield very pure quinacridone pigments and allow the synthesis of only one isomer of substituted quinacridones.
