摘要:The present invention relates to a novel method of synthesis of unsolvated mixed cation borohydrides of a general formula M x M′ y (BH 4 ) z , where M and M′ stand for metal cations, x, y, and z are stoichiometric coefficients. The method of synthesis according to the present invention is characterised in that the precursors having a general formula M[A n ] u and [Cat] v M′(BH 4 ) w are used for the synthesis, where [An] stands for a weakly coordinating anion; [Cat] stands for weakly coordinating cation; u, v, and w are the stoichiometric coefficients; and the synthesis is carried out under an inert to the reagents atmosphere—according to the general reaction equation: x M[An] u +y [Cat] v M′(BH 4 ) w →M x M′ y (BH 4 ) z +xu [Cat][An] where z=yw, xu=yv; M x M′ y (BH 4 ) z is the product of the reaction.

摘要:Methods for the preparation of inorganic nanoparticles capable of fluorescence, wherein the nanoparticles consist of a host material that comprises at least one dopant. The synthesis of the invention in organic solvents allows to gain a considerably higher yield compared to the prior art synthesis in water. All kinds of objects can advantageously be marked and reliably authenticated by using an automated method on the basis of a characteristic emission. Further, the size distribution of the prepared nanoparticles is nartower which renders a subsequent size-selected separation process superfluous.

摘要:The present invention provides a new approach to the synthesis of 2-amino-tetrahydrocarbazole-propanoic acid, a key intermediate for the synthesis of Ramatroban. More specifically, a synthesis of 2-amino-tetrahydrocarbazole- propanoic acid which includes oxidizing an aminocyclohexanol to form an aminocyclohexanone, condensing the aminocyclohexanone to form a tetrahydrocarbazole, deprotecting the tetrahydrocarbazole to yield a racemic mixture of a tetrahydrocarbazole, resolving the racemic mixture to obtain a yield mixture with an enantiomeric excess of one enantiomer over another, alkylating the excess enantiomer to yield an alkyl ester, and hydrolyzing the alkyl ester to yield 2-amino-tetrahydrocarbazole-propanoic acid.
