摘要:
The present invention relates to the method of preparing of ezetimibe and in particular to novel intermediates for its synthesis and an improved process for preparing such intermediates. Said intermediates may be obtained in high yields and purity in a fast and cost efficient manner. The present invention relates to a novel crystalline form of ezetimibe as well.
摘要:
The present invention relates to a compound of Formula (I) in particular compounds of formula (Ia), the use of a therapeutically effective amount of one or more compounds of formula (I) or (Ia) as a broad-spectrum antibiotic and the use of a pharmaceutical composition comprising said compounds for the treatment of bacterial infections in humans or animals.
摘要:
The invention relates to novel organo phosphorus P-chiral optically active compounds of formula (I) having a hydroxyl, mercapto, amino, carboxyl, sulfonyl group on aryl near a phosphorus atom, to the preparation and the use thereof in then asymmetrical catalysis of unsaturated compounds. Novel acylphosphine optically pure ligands embodied in the form of transition metal complexes exhibit an increased activity and enantloselectivity, in particular in asymmetrical hydrogenation, in comparison with the same type Uganda such as DiPAMP.
摘要:
The present disclosure relates to an improved process for the preparation of enantiomerically enriched alcohols of Formula (I), from the corresponding ketone of Formula (II), by asymmetric transfer hydrogenation, using a hydrogen donor, catalyzed by a ruthenium or rhodium complex of an optically active N-sulfamoyl-1,2-diamine. R is as defined herein.

摘要:
Cover for a vessel aperture manufactured in one piece notably through the casting of a plastic material, comprising in part a channeled frame adapted to be sealed or otherwise attached to the outer edges of a vessel aperture, a cover adapted to fit into the frame in closed position, the frame and cover being connected by a zone of liaison constituting a hinge and formed in a single piece interdependent with the frame and cover from the time they were cast with the cover piece in the open position.
