Definitions

  • the invention relates to chiral organoboranes, processes for their preparation and their use in particular as an asymmetric reducing agent.
  • a subject of the invention is therefore compounds of general formulas I and II
  • R 1 and R 2 independently represent a hydrogen atom or an alkyl or cycloalkyl radical, or R 1 and R 2 together represent a divalent saturated hydrocarbon group;
  • Xl represents a halogen atom
  • X2 represents a hydrogen or halogen atom
  • halogen represents a fluorine, chlorine, bromine or iodine atom, preferably fluorinated, chlorine, and bromine.
  • alkyl preferably represents an alkyl radical having from 1 to 6 carbon atoms, linear or branched, and in particular an alkyl radical having from 1 to 4 carbon atoms such as the methyl, ethyl, propyl, isopropyl, butyl radicals , isobutyl, sec-butyl and tert-butyl.
  • the saturated cycloalkyl radicals can be chosen from radicals having from 3 to 7 carbon atoms such as the cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, cycloheptyl or cyclooctyl radicals, optionally substituted by a lower alkyl group.
  • the expression saturated divalent hydrocarbon group comprises from 6 to 8 carbon atoms and can be represented by a bicyclo group [5,1,1], [4,1,2], [3,1,3], [ 4.1.1], [3.1.2], [3.1.1] or [2.1.2], and preferably of the type [3.1.3].
  • a subject of the invention is also a process for preparing the compounds of general formula I as defined above, characterized in that a compound of general formula III is reacted
  • suitable unsaturated hydrogenated compound represents a hydrocarbon compound comprising one or two double bond (s).
  • organic group represents an alkyl or aryl radical, and preferably an alkyl radical such as tert-butyl.
  • a cycloalkyldiene comprising from 6 to 8 carbon atoms
  • R] and R2 together represent a divalent saturated hydrocarbon group of 6 to 8 atoms respectively.
  • the production of an alkyl and / or cycloalkyl radical on the boron atom of the compound of formula I is obtained by reacting the corresponding alkene and / or cycloalkene (s) respectively, with the compound of formula III.
  • the invention also relates to a process for the preparation of the compounds of general formula II as defined above.
  • the process for the preparation of a compound of formula II in which X ⁇ has the meaning indicated above and X 2 represents hydrogen is characterized in that a compound of general formula III as defined below is reacted above, with one mole of a hydrogen halide of formula HXi, in which Xj has the meaning indicated above.
  • the process for the preparation of a compound of formula II in which Xi has the meaning indicated above and X 2 represents a halogen is characterized in that a compound of general formula III as defined above is reacted , with one mole of a hydrogen halide HXi and one mole of the hydrogen halide HX2.
  • X] and X2 can represent the same halogen atom.
  • the starting compound IH is known; it can be prepared by hydroboration of 2-myrtényl 1,3-dithiane with diborane or by a complex of diborane with a Lewis acid (patent EP 61408).
  • the compounds of formula I and II can thus be prepared in optically active form, from compound IH in optically active form.
  • the compounds of the present invention are useful as an asymmetric reducing agent.
  • a subject of the invention is therefore also the use of the compounds of formula I and II for asymmetric reductions.
  • the compounds of the present invention are used for the stereospecific reduction of ketone or imine function (s).
  • the stereospecific reduction of ketone or imine consists in reacting the ketone or rimine with an enantiomer of a compound of general formula I or H.
  • the white solid is collected in 20 ml of anhydrous tetrahydrofuran and used as such in the reductions.
  • the compound (+) 2 is crystallized from hexane (530 ml), to give 52.1 g with a composition 98.2% (-) / 1.8% ( +).
