An efficient conversion of olefins to ketones was achieved by the use of molecularoxygen and triethylsilane in the presence of a catalytic amount of cobalt(II) complex of porphyrin. The oxidation was accelerated remarkably in alcohols and had chemoselectivity for conjugated olefins.
在催化量的卟啉钴 (II) 络合物存在下,通过使用分子氧和三乙基硅烷,实现了烯烃到酮的有效转化。在醇中氧化显着加速并且对共轭烯烃具有化学选择性。
One-Pot Preparation of Alcohols from Aromatic Olefins and Acrylic Acid Derivatives by Cobalt(II) Porphyrin-Catalyzed Reductive Oxygenation Followed by Reduction with Trimethyl Phosphite
acid derivatives were converted to benzyl alcohols and α-hydroxyalkanoic acid derivatives in good yields by the reductive oxygenation with oxygen and triethylsilane in the presence of a catalytic amount of cobalt(II) porphyrin followed by treating the reaction mixture with trimethyl phosphite.
在催化量的钴 (II) 卟啉存在下,通过氧和三乙基硅烷的还原氧化,各种芳族烯烃和丙烯酸衍生物以良好的收率转化为苯甲醇和 α-羟基链烷酸衍生物,然后用三甲基卟啉处理反应混合物。亚磷酸盐。

The present invention relates to compounds of Formula (1), or pharmaceutically acceptable salts thereof and their pharmaceutical compositions, wherein variables are as defined herein, which are useful as modulators of the activity of lysophosphatidic acid (LPA).
tertiary benzylic positions of methylbenzylethers or unsymmetrical dibenzyl ethers and is also applicable to direct allylation, alkynylation, and cyanation reactions, as well as the azidation. The present methodologies provide not only a novel chemoselectivity but also the advantage of shortened synthetic steps, due to the direct process without the deprotection of the methyl and benzylethers.
The photooxidation of phenylcyclopropane, styrene, and indene using 9,10-dicyanoanthracene-Cu(BF4)2 sensitizer system in acetonitrile-alcohol(3:1) solutions affords the corresponding 1,3-dialkoxy and 1,2-dialkoxy compounds.
