The resolution of racemic 2,3-methanopyroglutamic acid (∇Glp) was accomplished using L- and D-Leu-NH2 and both isomers were hydrolyzed to give optically active (Z)-2,3-methanoglutamic acids1) (∇ZGlu), respectively. The optical rotations of these samples were compared with ∇ZGlu obtained by hydrolysis of ∇Glp prepared by oxidation of (2S,3R)- or (2R,3S)-2,3-methanoproline1) (∇Pro), the absolute configurations
Active carrier that consists of a carrier base (
1
) and attached linkers containing activated linker functional groups. The active carrier contains two or more different activated linker functional groups. A process for the production of the active carrier that comprises a carrier base (
1
) and linkers containing activated linker functional groups. Steps of the process: a) binding of a linker containing one or more linker functional groups to the carrier base (
1
), through the carrier functional groups; and b) reacting the linker functional groups of the linkers bound to the carrier base in step a) with two or more different activating reagents simultaneously. Use of the active carrier, during which the surface of the active carrier is contacted with one or more solution of small molecules.
