Abstract:
The present invention relates to a process for the preparation of a diastereomerically enriched compound, wherein a first compound according to formula (I), is contacted with a second compound according to formula (II), to form a third compound according to formula (III), whereby the compound according to formula (III) is subsequently reduced and thereby converted into a compound according to formula (IV), in which formulas: R1=a cycloalkyl group whereby R1 # R2, R2=a substituted or unsubstituted: (cyclo)alkyl group, (cyclo)alkenyl group, aryl group, cyclic or acyclic heteroalkyl group or heteroaryl group, R3=an alkyl group, R4=a substituted or unsubstituted: phenyl- or naphthyl-group, *=a chiral center. The invention furthermore relates to a diastereomerically enriched compound according to formula (IV) and its use in the preparation of pharmaceutical and agrochemically active compounds. The invention further relates to a process for the preparation of enantiomerically enriched compounds of formula (V), through hydrogenolysis of diastereomerically enriched compounds of formula (IV), wherein R1 and R2 have the meanings given above.

Abstract:
A magnetic resonance tomography device, wherein vibrations of device components, particularly in the low frequency range, are attenuated, as a magnet body surrounded by a magnet shell, which surrounds and defines an inner area. A gradient coil system is disposed in the inner area and an inner encapsulation cylinder also is disposed therein. The magnetic shell and the gradient coil system are externally and acoustically sealed from the inner encapsulation cylinder, and from a capsule. The capsule is formed as a three-layer system, including a cover layer, a full foam layer and a partial foam layer.
Abstract:
In an MR tomography apparatus damping laminated sheets are provided for reducing vibrations The MR tomography apparatus has a magnet body which is surrounded by a magnet housing which surrounds and delimits an interior volume. A gradient coil system is located in this interior volume. On an inner side of the magnet housing that delimits the interior volume, a damping laminated sheet structure is provided for absorbing acoustic vibrations which are produced on switching of the gradient coil system.
Abstract:
A predetermined area is protected from the disturbing usage of mobile terminals (e. g. cell phones) of a wireless communication system. Mode change information is sent over a system information message of a broadcast channel to change the operating mode (e. g. to deactivate) of the mobile terminal. This mode change information contains information, such as, the duration of the mode change, a reason for the mode change and information on groups of mobile terminals that will be exempted from the mode change. Additionally, the mobile terminal transmits an alarm signal to the user if the user is approaching a predetermined protected area.
