    • The present invention provides an industrially advantageous method for producing an optically active naphthalene compound useful as a therapeutic agent for dermatitis or the like. Specifically, the present invention provides a method for producing an optically active naphthalene compound [I], which comprises: a step of reacting a compound [a-1] and a compound [b-1] with each other in the presence of a base and a catalyst that is composed of a Pd compound and a tertiary phosphine ligand (step a); a step of asymmetrically hydrogenating a compound [c-1] in the presence of a hydrogen donor and a complex that is prepared from a ruthenium compound and a chiral ligand, or alternatively in the presence of an optically active oxazaborolidine compound (a CBS catalyst) and a boron hydride compound (step b); and a step of treating a compound [d-1] with a reducing agent (step c). (In the above formulae, Ra and Rb represent the same or different lower alkyl groups; and X1 represents a halogen atom.).
    • 本发明提供了用于制造用作皮炎等的治疗剂的光学活性萘化合物的工业上有利的方法。 具体而言,本发明提供了一种光学活性萘化合物[I]的制造方法,其特征在于,在碱的存在下,使化合物[a-1]和化合物[b-1] 和由Pd化合物和叔膦配体组成的催化剂(步骤a); 在氢供体和由钌化合物和手性配体制备的络合物的存在下,或者在光学活性的恶唑硼烷化合物(CBS催化剂)存在下,不对称地氢化化合物[c-1] 和硼氢化合物(步骤b); 和用还原剂处理化合物[d-1](步骤c)的步骤。 (上述式中,Ra和Rb表示相同或不同的低级烷基,X1表示卤素原子。

    • A radio selective calling reception system for limiting recipients participating in a group call limited by setting up a radio selective calling receiver, includes a reception unit, a switch, a numerical string search unit, a numerical string storage unit, a message storage unit, a message unit, a display unit, and a controller connected to each of the foregoing. By manipulating the switch, a message received as a result of a conference call is demodulated by the reception unit, and its included numerical string is extracted by the controller and compared with numerical strings stored in the numerical string storage unit by the numerical string search unit. As a result of a search, a received message is stored in the message storage unit, and the message reception notification operation is performed by the message unit and a loudspeaker connected to the message unit. Since an arbitrary numerical string for sub-group identification is set in the radio selective calling receiver to limit reception for a group call, the storing of unnecessary messages is eliminated, and the memory space provided for message storage is more effectively employed. Accordingly, the load placed on a message transmitter is reduced, and superior radio selective calling receiver is provided for a user. Furthermore, a sub-group is flexibly set or altered and a waste of a finite source, such as individual numbers, is eliminated.
    • 一种无线电选呼接收系统,用于限制通过建立无线电选呼接收机而参与组呼的接收者,包括接收单元,开关,数字串搜索单元,数字串存储单元,消息存储单元, 消息单元,显示单元和连接到上述各个的控制器。 通过操纵开关,由接收单元解调作为电话会议结果接收到的消息,并且由控制器提取其包含的数字串,并通过数字串搜索单元与数字串存储单元中存储的数字串进行比较 。 作为搜索的结果,接收的消息被存储在消息存储单元中,并且消息接收通知操作由消息单元和连接到消息单元的扬声器执行。 由于在无线电选择呼叫接收机中设置用于子组识别的任意数字串,以限制群组呼叫的接收,消除了不必要消息的存储,更有效地采用提供用于消息存储的存储空间。 因此,放置在消息发送器上的负载减少,并且为用户提供了优越的无线电选呼接收机。 此外,子组被灵活地设置或改变,并且消除诸如单个号码的有限源的浪费。
