Serum deprivation-induced neuronal-like PC12 cell apoptosis was used as an ischemic/hypoxic model to screen neuroprotective compounds from the rhizomes of Gastrodia elata, a traditional Chinese medicine. Two active compounds, bis(4-hydroxybenzyl)sulfide (
Selective Hydrogenation of Nitriles to Primary Amines Catalyzed by a Polysilane/SiO2-Supported Palladium Catalyst under Continuous-Flow Conditions

, p. 211 - 215 (2017)
Hydrogenation of nitriles to primary amines with heterogeneous catalysts under liquid-phase continuous-flow conditions is described. Newly developed polysilane/SiO2-supported Pd was found to be an effective catalyst and various nitriles were converted into primary amine salts in almost quantitative yields under mild reaction conditions. Interestingly, a complex mixture was obtained under batch conditions. Lifetime experiments showed that this catalyst remained active for more than 300 h (TON≥10 000) without loss of selectivity and no metal leaching from the catalyst occurred. By using this continuous-flow hydrogenation, synthesis of venlafaxine, an antidepressant drug, has been accomplished.

In this study, ten ω-transaminases (ω-TAs) have been investigated to efficiently catalyze the synthesis of twenty-four functionalized benzylamines and pyridylmethylamines. We optimized the reactions, screened suitable amino donors and compared ω-transaminases activities for all aromatic aldehyde substrates. Under the optimized conditions, eighteen aromatic amines have been obtained with 60.4%–96.6% conversions and isolated only via simple extraction and recrystallization with 18.5%–81% yields on a preparative scale. Furthermore, we first immobilized the Bm-STA onto the MOFs via the physical adsorption to overcome the limitation of free enzyme and improve their industrial applications. The obtained Bm-STA/UiO-66-NH2 composites exhibited not only high enzymes loading (80.4 mg g?1) and enzyme activity recovery (95.8%), but also the better reusability, storage stability, pH stability and the tolerance to acetone and DMF.

1,2,3-Trimethoxypropane (1,2,3-TMP) was prepared from glycerol in one step in good yield and selectivity by phase transfer catalysis. According to OECD guidelines, a toxicity study was realized for this compound. It revealed that 1,2,3-TMP has a low acute toxicity, no skin sensitization, no mutagenicity and no ecotoxicity in an aquatic environment. This compound was also used as a solvent for the reduction of organic functions using either aluminium hydride or 1,1,3,3-tetramethyldisiloxane (TMDS) as a benign hydride source. In particular, a new process for the reduction of nitriles to amines in 2-MeTHF and in 1,2,3-TMP was developed, using TMDS in combination with copper triflate (Cu(OTf)2).
