3. Eiji Yamamoto, Kodai Wakafuji, Yuho Furutachi, Kaoru Kobayashi, Takashi Kamachi, Makoto Tokunaga, Dynamic Kinetic Resolution of N-Protected Amino Acid Esters via Phase-Transfer Catalytic Base Hydrolysis, ACS Catalysis, 10.1021/acscatal.8b00693, 8, 7, 5708-5713, 2018.07, Asymmetric base hydrolysis of α-chiral esters with synthetic small-molecule catalysts is described. Quaternary ammonium salts derived from quinine were used as chiral phase-transfer catalysts to promote the base hydrolysis of N-protected amino acid hexafluoroisopropyl esters in a CHCl3/NaOH (aq) via dynamic kinetic resolution, providing the corresponding products in moderate to good yields (up to 99%) with up to 96:4 er. Experimental and computational mechanistic studies using DFT calculation and pseudotransition state (pseudo-TS) conformational search afforded a TS model accounting for the origin of the stereoselectivity. The model suggested π-stacking and H-bonding interactions play essential roles in stabilizing the TS structures..
4. Isao Nakamura, Haruno Murayama, Makoto Tokunaga, Mitsutaka Okumura, Tadahiro Fujitani, Adsorption and thermal reactivity of dimethyl trisulfide on a Au(111) single-crystal surface, Surface Science, 10.1016/j.susc.2018.07.012, 677, 186-192, 2018.11, We investigated the adsorption and thermal reactivity of dimethyl trisulfide (DMTS, CH3SSSCH3) on a Au(111) single-crystal surface. X-ray photoelectron spectroscopy results indicated that at exposure temperatures of 100–300 K, DMTS dissociatively adsorbed as CH3S and CH3SS. That the dissociative adsorption rate was independent of exposure temperature suggested that DMTS dissociation on Au proceeded without an energy barrier at >100 K. In contrast, the thermal reactions of the adsorbed CH3S and CH3SS varied strongly with formation temperature. Specifically, after CH3S and CH3SS formed on Au(111) at 100 K, increasing the temperature resulted in associative desorption of CH3S as dimethyl disulfide (CH3SSCH3) and coupling reaction of CH3SS to ethane and atomic sulfur. In contrast, after CH3S and CH3SS formed at 150 K, increasing the temperature resulted not only in these two reactions but also in production of dimethyl disulfide and atomic sulfur by reaction between CH3S and CH3SS. At formation temperatures of 200 and 300 K, the only reaction observed was that between CH3S and CH3SS. These results suggest that the surface structure of the adsorbed species formed by DMTS dissociation on Au(111) depended on formation temperature. Specifically, at 100 K, dissociation of DMTS resulted in formation of CH3S and CH3SS islands on the Au(111) surface, whereas the two species were randomly adsorbed at higher formation temperatures..

Compared with a conventional adsorbent, activated carbon, Au/SiO2 selectively reduced the DMTS concentration in Japanese sake without decreasing the concentrations of other aromatic components. DFT calculations revealed that the selective adsorption of DMTS occurred through the formation of a stable intermediate. The size of the supported Au NPs was controlled by the preparation conditions and determined from TEM observations and XRD measurements, and the size was ranged from 2.4 nm to 30 nm. Au/SiO2 having Au NPs with a diameter of 2.4 nm adsorbed DMTS the most efficiently. Smaller Au NPs showed better DMTS adsorption capabilities because larger amounts of Au atoms were exposed on their surfaces in the size range of this study. Langmuir-type monolayer adsorption and one-to-one binding of Au–S are proposed to occur based on an adsorption isotherm experiment. Even though significant differences of the fruity aroma score were not observed in the sensory evaluation between Au/SiO2 and activated carbon for this less aromatic Japanese sake, Au/SiO2 selectively decreased the DMTS concentration in the instrumental analysis..
