    Description / Table of Contents: A Boraadamantane Ringsystem with B, N-Betaine StructureBisalkylation of primary amines with diepoxides (10) leads to 1-alkyl-3,5-piperidinediols (11) which are oxidized to N-oxides (12). These react with areneboronic acids to give boron-nitrogen-betaines with an adamantoid (8) or bicyclic (16)ringsystem.
    Notes: Die Bisalkylierung primärer Amine mit Diepoxiden (10) führt zu 1-Alkyl-3,5-piperidindiolen (11), die zu N-Oxiden (12) oxidiert werden. Durch Reaktion von 12 mit Arylboronsäuren erhält man Bor-Stickstoff-Betaine mit adamantoidem (8) oder bicyclischem (16)Ringsystem.

    Description / Table of Contents: Boron-Nitrogen Betaines with Bicyclic (“Cage”) StructureN-Oxidation of 2-dimethylamino-2-methyl-1,3-propanediol (4) yields the tridentate ligand 5 which reacts with aryldihydroxyboranes to form a 1-borabicyclo[2.2.2]octane system with B,N-betaine structure 8.
    Notes: N-Oxidation von 2-Dimethylamino-2-methyl-1,3-propandiol (4) ergibt den dreizähnigen Liganden 5, der mit Aryldihydroxyboranen unter Bildung eines 1-Borabicyclo[2.2.2]octan-Systems mit B,N-Betain-Struktur 8 reagiert.
