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.

摘要:Substantially entiomerically pure 3,3-disubstituted-5-monosubstituted pyrrolidin-2-ones of formula (I) in which R2 is hydrogen and R and R1 are as defined in the description, are useful chiral auxiliaries for the synthesis of chiral molecules. The 1-position nitrogen atom is a reactive centre to which may be reversibly coupled a wide range of groups containing prochiral centres, the substituent at the 5R- or 5S- position influencing the stereoselectivity of reactions performed on such groups. Compounds in which R2 is an acyl group containing a prochiral centre are also claimed.

摘要:The present invention aims at solving the problems of conventional methods for producing an 18 F-labeled compound, that is, the problem of purification of a compound in a liquid phase synthesis method and the problem of an insufficient yield due to the reduction of reactivity in a solid phase synthesis method. There is provided a method for producing an 18 F-labeled compound including: allowing a high molecular compound containing a residue of a precursor compound to be labeled and a residue of a phase transfer catalyst in the molecule thereof to react with 18 F − ; and removing the 18 F-labeled compound from the high molecular compound.
