摘要:The present invention relates to the stereoselective synthesis of (4aS,7aS)-octahydro-1H-pyrrolo[3,4-b]pyridine, as well as the conversion thereof, to give Moxifloxacin. Particularly, the present invention relates to a method for the synthesis of (4aS,7aS)-octahydro-1H-pyrrolo[3,4-b]pyridine of formula (I) comprising: (a) the optical resolution by enzymatic hydrolysis of the intermediate dialkyl-1-alkylcarbonylpiperidine-2,3-dicarboxylate racemate of formula (II) to give, following isolation, the intermediate dialkyl-(2S,3R)-1-alkylcarbonyl-piperidine-2,3-dicarboxylate of formula (III) in which AIk is a straight or branched C1-C5 alkyl group; (b) the conversion of the intermediate (III) to (4aR,7aS)-1-alkylcarbonylhexahydrofuro[3,4-b]pyridine-5,7-dione of formula (IV) in which AIk has the meanings set forth above; (c) the conversion of the intermediate (IV) to (4aS,7as)-octahydro-1H-pyrrolo[3,4-b]pyridine of formula (I) with an optical purity above 99%.

权利人:LEAR MARTIN JAMES; TAN KEVIN SHYONG WEI
摘要:This invention includes a fluorophore-tagged antimalarial represented by the following structural formula (1) or a salt thereof. This invention relates to the synthesis of fluorophore-tagged antimalarials and describes the synthesis of a fluorophore-tagged antimalarial. These fluorophore-tagged antimalarials can be used to image live cells to determine the location of the antimalarial in the cell, identify drug resistance and growth related pathways in Plasmodium isolates, identify new drug targets and chemo-sensitizers to reverse drug resistance.

摘要:The invention relates to a new process for preparing active esters or carboyxlic acids, which consists in reacting a carboxylic acid, in the presence of an agent for binding hydrohalic acid, with a carbonate of formula: ##STR1## in which R 1 denotes either a radical of formula ##STR2## in which R 3 and R 4 , which may be identical or different, are not hydrogen atoms and denote organic radicals which may be substituted or unsubstituted and saturated or unsaturated, and may or may not be bound to a polymer, and which can be joined together to form a hetero-cyclic system with the nitrogen, atom, n or a substituted or unsubstituted aryl radical which may or may not be bound to a polymer, n R 2 denotes a hydrogen atom, an aliphatic or cycloaliphatic radical which may be substituted or unsubstituted and saturated or unsaturated, or a substituted or unsubstituted aromatic radical, n and X denotes a halogen atom. n This process is especially useful for the synthesis of active esters of N-protected amino acids. The invention also relates to the new carbonates described above and the method of producing them, which consists in reacting an alpha-halogenated chloroformate of formula: n n R.sup.2 --CHX--O--COCl n n with an alcohol of formula R 1 OH in an inert solvent medium in the presence of an organic or inorganic base.
