摘要:
A process for the preparation of oxazolidinone derivatives, in particular [(S)—N-[[3-(3-fluoro-4-morpholinyl)phenyl]-2-oxo-5-oxazolidinyl]methyl]-acetamide] (linezolid), and novel intermediates useful for the synthesis thereof.
摘要:
A process for the preparation of (S)(+)-3-(aminomethyl)-5-methylhexanoic acid (pregabalin) of formula (I) or a salt thereof, comprising the reaction of a compound of formula (II) with an alcohol ROH, in the presence or absence of enzyme, to give a compound of formula (III) as herein defined the transformation of a compound of formula (III) into a compound of formula (VI) or (VIII) as herein defined, and the subsequent hydrolysis of a compound of formula (VI) or (VIII), to give pregabalin.

摘要:
Process for the preparation of crystalline anhydrous (R)-2-[[[3-methyl-4-(2,2,2-trifluoroetoxy)-2-piridyl]methyl]sulphinyl]benzimidazole (dexlansoprazole).
摘要:
A process for the preparation of Imiquimod and novel hydroxylamino and hydrazine derivatives, useful as intermediates in its preparation. The process includes the reaction of 4-chloro-1-isobutyl-1H-imidazo[4,5-c]quinoline, of formula (I) with a compound of formula (II) NH2—X (II) wherein X is an —OR or —NR1R2 group, in which R is hydrogen, a C1-C6 alkyl, aryl-C1-C4 alkyl, aryl or —SO3H (sulfonic) group; and each of R1 and R2 is independently hydrogen, a C1-C6 alkyl, aryl-C1-C4 alkyl, aryl or —SO2R3 group, in which R3 is an aryl group and, if necessary, the reaction with a reducing agent.
