标题:Synthesis of macrocyclic tetraamido compounds and new metal insertion process
发明人:HORWITZ COLIN P; GHOSH ANINDYA
权利人:UNIV CARNEGIE MELLON
摘要:An improved method of synthesizing a macrocyclic tetraamido compound includes protecting the amino portion of an amino carboxylic acid to form a protected amino carboxylic acid; exposing the protected amino carboxylic acid to a first solvent, preferably a hydrocarbon solvent, such as toluene or 1,2-dichloroethane, dichloromethane, dibromomethane and 1,2-dibromoethane. The carboxylic acid portion of the protected amino carboxylic acid is then converted to an activated carboxylic acid by one of esterification or acid halide formation, to form a protected amino activated carboxylic acid derivative. The protected amino activated carboxylic acid derivative is reacted with a diamine in the presence of a second solvent, such as THF or ,2-dichloroethane, dichloromethane, dibromomethane and 1,2-dibromoethane, to form a protected diamide diamine intermediate. Following deprotection, the diamide diamine intermediate is reacted with an activated diacid, such as an activated malonate, oxalate or succinate derivative to form the macrocyclic tetraamido compound. The macrocyclic tetraamido compound may further be complexed with a transition metal.

摘要:The present invention relates to novel manganese complexes and their use, inter alia, for homogeneous catalysis in (1) the preparation of imine by dehydrogenative coupling of an alcohol and amine; (2) C—C coupling in Michael addition reaction using nitriles as Michael donors; (3) dehydrogenative coupling of alcohols to give esters and hydrogen gas (4) hydrogenation of esters to form alcohols (including hydrogenation of cyclic esters (lactones) or cyclic di-esters (di-lactones), or polyesters); (5) hydrogenation of amides (including cyclic dipeptides, lactams, diamide, polypeptides and polyamides) to alcohols and amines (or diamine); (6) hydrogenation of organic carbonates (including polycarbonates) to alcohols or hydrogenation of carbamates (including polycarbamates) or urea derivatives to alcohols and amines; (7) dehydrogenation of secondary alcohols to ketones; (8) amidation of esters (i.e., synthesis of amides from esters and amines); (9) acylation of alcohols using esters; (10) coupling of alcohols with water and a base to form carboxylic acids; and (11) preparation of amino acids or their salts by coupling of amino alcohols with water and a base. (12) preparation of amides (including formamides, cyclic dipeptides, diamide, lactams, polypeptides and polyamides) by dehydrogenative coupling of alcohols and amines; (13) preparation of imides from diols.

权利人:PHARMACIA CORP
摘要:The present invention relates to methods for the stereospecific synthesis and for the enantiomeric enrichment of β-amino acids. A novel D-β-aminotransferase, which exhibits stereoselectivity for D-β-phenylalanine, (D-3 amino-3-phenylpropinine acid) was purified from a newly-isolated strain of Variouorax paradoxus . A novel L-β-aminotransferase was purified from a newly-isolated strain of Alcaligenes eutrophus . The D- and L-β-aminotransferases can be used to facilitate the stereoselective biosynthesis of β-D-phenylalanine or β-L-phenylalanine, from a mixture of L-glutamic acid or L-alanine, respectively, and 3-keto-3-phenylpropionic acid in the presence of the cofactor pyridoxal phosphate.
