  通过Pd催化的顺序芳基化反应合成不对称的三芳基乙腈：一种新的三芳基和四芳基甲烷合成方法

  摘要：

  据报道，通过连续的钯催化的氯乙腈的芳基化反应，可以选择性合成多芳基化的乙腈。这三个芳基是通过Pd催化的Suzuki-Miyaura交叉偶联反应安装的，然后是背靠背的C-H芳基化反应，分三步提供三芳基乙腈，任何一步均不发生过度芳基化。三芳基乙腈产物可以转化为高度官能化的物质，包括四芳基甲烷。这种新策略可从简单易得的起始原料中快速获得各种不对称的三芳基和四芳基甲烷衍生物。

  The present invention provides a catalyst used for manufacturing an optically active carbonyl compound by selective asymmetric hydrogenation of an α,β-unsaturated carbonyl compound, which is insoluble in a reaction mixture, and a method for manufacturing the corresponding optically active carbonyl compound. Particularly, the invention provides a catalyst for obtaining an optically active citronellal useful as a flavor or fragrance, by selective asymmetric hydrogenation of citral, geranial or neral. The invention relates to a catalyst for asymmetric hydrogenation of an α,β-unsaturated carbonyl compound, which comprises: a powder of at least one metal selected from metals belonging to Group 8 to Group 10 of the Periodic Table, or a metal-supported substance in which the at least one metal is supported on a support; an optically active peptide compound; and an acid, and also relates to a method for manufacturing an optically active carbonyl compound using the same.

  An object of the present invention is to provide a method for manufacturing an optically active menthol having fewer steps, which generates less environmentally polluting waste because a catalytic reaction is involved in all of the steps, and is capable of saving a production cost. The present invention relates to a method for manufacturing an optically active menthol, including the following steps: A-1) asymmetrically hydrogenating at least one of geranial and neral to thereby obtain an optically active citronellal, B-1) conducting a ring-closure reaction of the optically active citronellal in the presence of an acid catalyst to thereby obtain an optically active isopulegol, and C-1) hydrogenating the optically active isopulegol to thereby obtain an optically active menthol.

  stannylated cyclopropanes to be made selectively and in excellent optical purity, this transformation also marks a rare case of diastereodivergent asymmetric catalysis. The products are amenable to stereospecific cross coupling with aryl halides or alkenyl triflates; these transformations appear to be the first examples of the formation of stereogenic quaternary carbon centers by the Stille reaction; carbonylative

  The use of novel inhibitors of potassium flux is disclosed for the treatment of inflammatory processes, such as multiple sclerosis, insulin-dependent (type I) diabetes mellitus, rheumatoid arthritis, peripheral neuritis and pulmonary hypertension. The compounds are also of use in treating and preventing stroke. These inhibitors have a high specificity for the IK1 channel and greater stability relative to non-fluorine substituted homologues.
