    摘要: The present invention provides a process for selectively producing an enantiomer at position 4 of an optically active compound in the cross aldol reaction of pyruvic acid and indole-3-pyruvic acid. The process comprises the step of reacting pyruvic acid with indole-3-pyruvic acid in the presence of an optically active α-amino acid containing a secondary amine and a metal ion.

    摘要: According to one embodiment, a MEMS memory microprobe includes a probe tip, a lever, and a base. The probe tip is arranged to oppose a recording medium and is brought into contact with the recording medium to perform recording or reproduction of information when a current or voltage is applied between them. In the probe tip, a plurality of electrodes used in the recording or reproduction and a plurality of support portions which form the probe tip together with the electrodes are alternately arranged, and the electrodes and the support portions form a single plane which opposes the recording medium.
