  Enantioselective reduction of ketoxime ethers with borane–oxazaborolidines and synthesis of the key intermediate leading to (S)-rivastigmine

  摘要：

  The reduction of representative alkyl aryl (E)-ketoxime O-benzyl ethers with borane catalyzed by terpene oxazaborolidines, derived from (1R)-nopinone and (1R)-camphor, gave the corresponding amines with 82-99% ee. Oxazaborolidines derived from (1S)-2-carene and (1S)-3-carene were less selective. (S)-1-(3-Methoxyphenyl)ethanamine (94% ee) the key intermediate in the synthesis of (S)-rivastigmine, was obtained by the reduction of (E)-1-(3-methoxyphenyl)ethanone O-benzyl oxime with borane/oxazaborolidine generated from (S)-valinol.

  enantioselective borane reduction of O-benzyloxime ethers to primary amines was studied under catalytic conditions using the spiroborate esters 5-10 derived from nonracemic 1,2-amino alcohols and ethylene glycol. Effective catalytic conditions were achieved using only 10% of catalyst 5 derived from diphenylvalinol in dioxane at 0 degrees C resulting in complete conversion to the corresponding primary amine in

  (EN) Asymmetric reduction of arylalkyl and pyridylalkyl ketoxime ether with borane catalyzed by several chiral spiroborates derived from non-racemic 1,2-amino alcohols are presented. Complete conversion of oxime to primary amine is highly dependant of the catalyst, source and amount of borane and temperature. The conversion and enantioselectivity is determined by the benzylic substitution of the oxime. After optimization, a catalyst derived from diphenyl valinol could, successfully, afford primary amines with good yield and enantioselectivity up to 99% ee. Using the developed methodology, other related non-racemic primary pyridyl alkyl methanamines were also prepared in high chemical yield and excellent enantioselectivity.(FR) L'invention concerne une réduction asymétrique d'éther de cétoxime d'arylalkyle et de pyridylalkyle avec du borane catalysé par plusieurs spiroborates chiraux dérivés de 1,2-amino alcools non racémiques. Une conversion complète d'oxime en amine primaire est extrêmement dépendante du catalyseur, de la source et de la quantité de borane et de la température. La conversion et l'énantiosélectivité sont déterminées par la substitution benzylique de l'oxime. Après optimisation, un catalyseur dérivé du diphényl valinol pourrait avec succès permettre d'obtenir des amines primaires avec un bon rendement et une énantiosélectivité s'élevant jusqu'à 99% ee. Au moyen de la méthodologie développée, d'autres pyridyl alkyl méthanamines primaires non racémiques ont également été préparées pour déboucher sur un rendement chimique élevé et une excellente énantiosélectivité.
