Abstract: In a process for the preparation of ring compounds via a combinatorial synthesis, the reaction procedure is based on a Suzuki coupling; subsequent halo-demetallation and finally a further Suzuki coupling. The Suzuki couplings are each carried out with a boronic acid or a boronic acid ester. The reaction procedure uses provides novel ring compounds and uses novel synthesis units used for this purpose. The novel ring compounds are suitable for use as constituents in liquid-crystalline mixtures.

Abstract: A device for aligning a guide template used in resecting a distal femur in a one-compartment joint replacement. The device includes first and second support members (12;5), at least one rod-like transverse coupler (10;12), and a guide template (20). The support members each include a support surface (3;6) that is adjustable to lie in one plane (1) and designed to bear against one condyle (24;25) of a femur (21). The transverse coupler is arranged parallel to a transverse axis (2), which, in its end portion, is connected to the first support member (12) and is releasably connectable to the second support member (5). The transverse axis (2) extends parallel to a plane (1). The guide template (20) is displaceable parallel to the plane (1) relative to the second support member (5) and releasably lockable thereon.
