标 题 :Method for the synthesis of DNA conjugates by micellar catalysis
发明人：BHAT AVINASH SHASHIDHAR; KLIKA SKOPIC MATEJA; BRUNSCHWEIGER ANDREAS; WEBERSKIRCH RALF
权利人:UNIV DORTMUND TECH
摘要:A method for the synthesis of a chimeric conjugate molecule by micellar catalysis that may form part of DNA-encoded compound libraries. A DNA-coupled organic starter molecule may be reacted with another organic compound, using a catalyst located within a micelle, to form a conjugate of an organic candidate compound coupled to a DNA identifier tag.

摘要:The present invention relates to novel Ruthenium catalysts and related borohydride complexes, and the use of such catalysts, inter alia, for (1) hydrogenation of amides (including polyamides) to alcohols and amines; (2) preparing amides from alcohols with amines (including the preparation of polyamides (e.g., polypeptides) by reacting dialcohols and diamines and/or by polymerization of amino alcohols); (3) hydrogenation of esters to alcohols (including hydrogenation of cyclic esters (lactones) or cyclic di-esters (di-lactones) or polyesters); (4) hydrogenation of organic carbonates (including polycarbonates) to alcohols and hydrogenation of carbamates (including polycarbamates) or urea derivatives to alcohols and amines; (5) dehydrogenative coupling of alcohols to esters; (6) hydrogenation of secondary alcohols to ketones; (7) amidation of esters (i.e., synthesis of amides from esters and amines); (8) acylation of alcohols using esters; (9) coupling of alcohols with water to form carboxylic acids; and (10) dehydrogenation of beta-amino alcohols to form pyrazines. The present invention further relates to the novel uses of certain pyridine Ruthenium catalysts.
