摘要:
An object of the present invention is to provide an optically active bicyclic γ-amino acid derivative in a high purity. The object can be attained by a mixture of compounds represented by the general formulas (I) and (I′), or a method for producing a compound represented by the general formula (VII) or a salt thereof via the compound (I): wherein R1 and R2 each represent a C1-6 alkyl group or the like; and R3 represents a cyano group or the like,
摘要:
It is an object of the present invention to provide a method for efficiently producing (1S,4S,5S)-4-bromo-6-oxabicyclo[3.2.1]octan-7-one (1), which is important as an intermediate compound for the production of an FXa-inhibiting compound. A method for producing (1S,4S,5S)-4-bromo-6-oxabicyclo[3.2.1]octan-7-one (1), which comprises treating an (R)-α-phenylethylamine salt of (S)-3-cyclohexene-1-carboxylic acid with 1,3-dibromo-5,5-dimethylhydantoin or N-bromosuccinimide in a solvent.
