  • Publication number: 20170152253
    Abstract: A process for preparing [(1R,2R)-4-oxo-1,2-cyclopentanedicarboxylic acid II, by the resolution of racemic 4-oxo-1,2-cyclopentanedicarboxylic acid (V), said process comprising: (a) reacting 4-oxo-1,2-cyclopentanedicarboxylic acid (V) with brucine or (1R,2S)-(?)-ephedrine, thus preparing the bis-brucine or bis-(1R,2S)-(?)-ephedrine salt of (V), and (b) precipitating selectively the bis-brucine or bis-(1R,2S)-(?)-ephedrine salt of (1R,2R)-4-oxo-1,2-cyclopentanedicarboxylic acid II, while the bis-brucine or bis-(1R,2S)-(?)-ephedrine salt of [(1S,2S)-4-oxo-1,2-cyclopentanedicarboxylic acid stays in solution; (c) liberating the acid II by removal of brucine or (1R,2S)-(?)-ephedrine from the precipitated salt obtained in step (b).

  • Patent number: 9227965
    Abstract: Disclosed is a process for the preparation of a cinchonidine salt of formula (IV) via an aqueous solution of a racemic 4-hydroxy-1,2-cyclopentanedicarboxylic acid, which is subjected to cyclization without removing water, by the addition of a water-miscible organic solvent to the aqueous solution and, again without removing water, adding cinchonidine to the aqueous-organic solvent solution so as to obtain the cinchonidine salt of the lactone acid. The cinchonidine salt is allowd to crystallize so as to obtain the enantiomerically purified crystalline lactone acid cinchonidine salt (IV). The enantiomerically pure salt is an intermediate in the synthesis of HCV inhibitor compound of formula (I).
