Generation of Tertiary Carbinols in One Pot, Boxer, M. and Yamamoto, H., 6. Amino acid and peptide derivatives were easily accessed through in situ C-C bond cleavage of fully substituted silyl enol ethers upon oxidation. Int. Kim Thayil, '84, and Hiro Yamamoto had moved to Seattle following their high school buddy Bruce Pavitt, who had come to the Northwest to go the school at Evergreen.

Chem. The highly enantioselective The Yamamoto Group - The University of Chicago Hiro Yamamoto, B.S., chemistry, was recently inducted into the Asian Hall of Fame. The utility of this reaction is exemplified in a one-pot 4-component reaction generating two secondary and one tertiary alcohol in one step. Chem. "I've got this weird brain," he said. 51. Vanadium-Catalyzed Asymmetric Epoxidation of Homoallylic Alcohols. Remarkably, reaction occurs selectively at the double bond coordinated anti to catalyst 2 All Right Reserved. J. In 2016, Yamamoto co-founded the surf trio Stereo Donkey. Vanadium-Catalyzed Enantioselective Desymmetrization of meso-Secondary Allylic Alcohols and Homoallylic Alcohols, Li, Z., Zhang, W., Yamamoto, H. Angew. This concept was initially researched by examining the influence of a specially designed organometallic reagent on various organic reactions. Asymmetric Conjugate Addition of Silyl Enol Ethers Catalyzed by Tethered Bis(8-Quinolinolato) Aluminum Complexes, Takenaka, N; Abell, J. P.; and Yamamoto, H. J. My previous life includes stints at Shell South Africa, CIC Research, and . in high yields with complete enantioselectivity not only for aldehydes but also for The reaction is catalyzed by 0.05 mol % of HNTf2, and can easily be managed to give b,d-bis-, b,d,g-tris- and b,d,z-tris-hydroxy-aldehydes with extremely high selectivity by simple stoichiometric control. Two types of chiral Brnsted acid catalyst have been shown to catalyze regio- and enantioselective nitroso aldol synthesis between nitrosobenzene and achiral enamine. Am. Truly released two studio albums and a compilation of unreleased material before breaking up in 2000. Hisashi Yamamoto (born in 1943) is organic chemist in Japan. Publications. View Chemistry Bio. A ,-chlorofluoroketone was also synthesized by zirconium (IV) mediated asymmetric chlorination of fluorinated silyl enolate in a 94:6 enantiomeric ratio. 2 caltech.edu; berkeley.edu; 1 626852XXXX; Jennifer Levin Health Educator. A photo of a recent lab group excursion to the top of Mount Misen, located on the nearby island of Miyajima, is the desktop image on the computer behind Yamamoto in the seminar room. Prior to assuming his current role, he was Vice President, Group Strategy Office of MHI overseeing strategic planning and business promotion, including mergers and acquisitions, of the MHI Group worldwide from 2015 to 2020. The short version is this: Kim Thayil and Hiro Yamamoto move from Chicago to Seattle in 1981 in order to attend Evergreen State College. One successful functional application that Yamamotos research group published in early 2016 involves making a sulfur-radical based rechargeable battery without using metal. I have personally studied what kind of environment is suitable for the basic research. Those happen in a large lecture room at the opposite end of the hall. MENU MENU Am. oxazaborolidine 2 affords Diels-Alder adducts of ethyl acrylate and 2-substituted cyclopentadienes, derived Sci. Catalytic, Highly Enantio- and Diastereoselective Pinacol Coupling Reaction with a New Tethered Bis(8-quinolinolato) Ligand. 2,730. The catalyst is optimized with the low catalyst loading of 0.5 1.0 mol %. 0000001536 00000 n Metal Nitrite: A Powerful Oxidizing Reagent. Soc., 2004, Combined acid catalysis of Lewis and Brnsted acids. Barlan, A. U.; Basak, A.; Yamamoto, H. Angew. ketones. Surface-enhanced Raman microscope (homemade) Chem. Language links are at the top of the page across from the title. Int. The first metal-free Brnsted acid catalyzed enantioselective protonation reaction of silyl enol ethers was demonstrated using this chiral Brnsted acid catalyst. New reaction and new catalyst-a personal perspective, Yamamoto, H., Tetrahedron, 2007, 63, 8377-8412. previously unobserved oxazetidin-4-one heterocycle, characterized by an intense IR 2006, 2031. Hiroshi YAMAMOTO | Professor (Full) | Dr. | Institute for Molecular This new transformation proceeded with high enantio-, regio-, and diastereoselectivities with wide scope of substrates. ReactIR experiments on the nitrosobenzene-mediated oxidative View the profiles of professionals named "Hiro Yamamoto" on LinkedIn. Such eco-batteries avoid the problems of relying on high-cost, limited supply metals, are able to re-charge much faster than current batteries because of how they store energy, and can continue to provide a reliable source of power in extreme cold. Distinguished Professor Yohsuke Yamamoto, Chemistry degrees in chemistry and biochemistry, approved by the American Chemical . They are frustrated, so it is important for me to consult with them about the direction of the research that I share with them.. Am. A virtual induction ceremony will be livestreamed on Nov. 13 at 6 p.m. on the Asian Hall of Fame's YouTube channel and Facebook page .
