• The Stereo-differentiating (Asymmetric) Hydrogenation of the C=O Double Bond with a Modified Nickel Catalyst. XXXV. A Facile Method for the Preparation of Optically Pure β-Diols

  The hydrogenation of RCOCH2COR over a Raney nickel catalyst modified with a mixture of tartaric acid and NaBr gave (R*, R*-RCH(OH)CH2CH(OH)R selectively with a high optical purity. The substrates with R=CH3–, CH3CH2–, CH3CH2CH2–, CH3(CH2)4CH2–, and Ph– were employed in this study. In all cases, the recrystallization of the hydrogenation product gave an optically pure (R*,R*)-isomer which was free from the (R*,S*)-isomer.

  在改性了酒石酸和NaBr混合物的Raney镍催化剂上，对RCOCH2COR进行氢化反应，得到了光学纯度较高的(R*, R*-RCH(OH)CH2CH(OH)R选择性产物。该研究中使用的底物包括R=CH3–、CH3CH2–、CH3CH2CH2–、CH3(CH2)4CH2–以及Ph–。在所有情况下，氢化产物的再结晶得到的都是光学纯的(R*,R*)-异构体，且不含(R*,S*)-异构体。

  Condensations of nonsymmetrical or symmetrical beta-diketones and unprotected sugars in aq NaHCO3 soln were explored. C-glucosyl and C-maltosyl derivatives bearing lipophilic residue of 8 or 11 carbon atoms were prepared efficiently using this one-step procedure. The amphiphilic properties of these compounds were demonstrated by measuring their CMC.

  The present invention deals with substituted benzyl diketones and a process for their preparation. Novel 2-(3',5'-dihydrocarbyl-4'-hydroxybenzyl)-1,3-diketones are prepared by reacting an N,N-dihydrocarbyl 2,6-dihydrocarbyl-4-aminomethylphenol with a 1,3-diketone and an alkyl halide in the presence of an alkali or an alkaline earth metal hydride. The resulting substituted benzyl diketones are useful as antioxidants into polymers, latices, liquid hydrocarbon fuels and lubricating oils.
