  • Method for the in situ preparation of chiral compounds derived from oxazaborolidine-borane complexes which are used in asymmetric reduction reactions
    Publication number: 20070055068
    Abstract: A process for the in situ preparation of chiral compounds derived from oxazaborolidine-borane complexes, wherein a metal borohydride, a Lewis base and an inorganic acid ester are brought together and an optically active amino alcohol and optionally a halide are then added. The compound obtained is a complex that is useful as a catalyst in asymmetric reduction reactions. The reaction is performed by adding the substance to be reduced, particularly prochiral ketones or ether oximes, in order to synthesize chiral alcohols or chiral amines.

  • Process for the synthesis of indanylamine or aminotetralin derivatives and novel intermediates
    Publication number: 20060052639
    Abstract: A process for preparing indanylamine and aminotetralin derivatives from indanone or tetralone oximes by acylating the oximes with an organic anhydride, followed by catalytic hydrogenation in the presence of an organic anhydride with subsequent hydrolysis is described. The process is commercially feasible providing indanylamine and aminotetralin derivatives in high yield that are useful as intermediates in the production of therapeutically active compounds. Also described are novel intermediates, 1-indanone O-acetyl oximes and 1-tetralone O-acetyl oximes.
