Abstract:
The present invention relates to a method and an apparatus for updating routing information in an in-vehicle communications network. A gateway for a vehicle according to an embodiment of the present invention includes: a multiple routing database (RDB) configuration database to record share configuration information including at least one rule for protocol conversion and individual configuration information; an RDB look-up table database to record a detailed protocol conversion scheme corresponding to the rule; an RDB configuration management module to configure a predetermined merge list by extracting a protocol conversion rule to be used in a corresponding vehicle with reference to the multiple routing database (RDB) configuration database and the RDB look-up table database; a message and signal routing management module to perform a protocol conversion for a received message or signal with reference to the merge list and the RDB look-up table database; and first to N-th communications interface modules which receive the message or signal, and transmit the protocol converted message or signal to a communications interface corresponding to the converted protocol. Accordingly, the present invention provides the gateway for the vehicle which may more efficiently update routing information.

본 발명은 구리 착물 촉매를 이용한 베타,베타-이중 치환된 알파,베타-불포화 니트릴 화합물의 환원방법을 통한 베타 위치에 키랄 중심을 갖는 니트릴 화합물의 제조방법에 관한 것으로, 보다 구체적으로 용매 및 구리 착물 촉매 존재하에서 하기 화학식 (I)의 β,β-이중 치환된 α,β-불포화 니트릴 화합물을 반응첨가물로서 C 2 ~ C 6 의 2차 또는 3차 알코올을 첨가하여 히드로실란과 환원반응시켜 하기 화학식 (II)의 베타 위치에 키랄 중심을 갖는 니트릴 화합물을 수득함을 특징으로 하는 베타 위치에 키랄 중심을 갖는 니트릴 화합물을 제조하는 방법에 관한 것이다. 본 발명의 제조방법은 촉매로서 구리(II) 아세테이트와 비스-포스핀 리간드를 사용하고, 수소원으로서 히드로실레인을 사용하므로써, 베타,베타 이중 치환된 알파,베타-불포화 나이트릴 화합물을 기존의 방법보다 더욱 빠르게 또한, 높은 입체 선택성과 수율을 갖는 물질로 환원시킬 수 있으며, 따라서 여러가지 약물 및 생리활성물질의 중간체로서 사용가능한 화학식 (II)의 화합물을 제조할 수 있다. 니트릴 화합물, 제조방법, 구리 촉매, 입체 선택성.
Abstract:
A method for preparing a beta-chiral nitrile compound useful as an intermediate for various drugs and physiologically active substances is provided to realize a higher reaction rate in the reduction of a beta,beta-disubsituted alpha,beta-unsaturated nitrile compound with high stereoselectivity and high yield via a simple process. A method for preparing a beta-chiral nitrile compound comprises a step of carrying out reduction of a beta,beta-disubstituted alpha,beta-unsaturated nitrile compound represented by the following formula (I) with hydrosilane in the presence of a solvent and a copper complex to obtain a beta-chiral nitrile compound represented by the following formula (II), as shown in the following reaction scheme 1. In reaction scheme 1, Ar is a phenyl or substituted or non-substituted C6-C15 aromatic group; and R is a C1-C8 alkyl, C6-C15 aromatic group or C6-C15 heteroaromatic group containing at least one of O, N and S.
