Although the mechanism of the surface-enhanced Raman scattering phenomena is becoming increasingly deeply understood, there are mysteries that still remain. "I've got this weird brain," he said. "I was kind of a D-I-Y punker," he laughed. in high yields with complete enantioselectivity not only for aldehydes but also for To the best of my skills, research themes of students are established taking into consideration the range and direction of each students' interests and according to their preferences, with consideration of the research theme presented by me. A. Odriozola , and G. A. Somorjai Cite this: J. Phys. Various ketone-derived silyl enol ethers, Grignard reagents, and dienes succeeded, generating relatively complex molecular architectures in a single step. Students are encouraged to actively make use of my knowledge and experiences. Products could be converted to the protected amino alcohols, which are frequently found in a number of important natural products. The scope of the present method turns out not to be limited to aromatic aldehyde derivatives, as cyclohexanecarboxaldehyde undergoes pinacolization as well (44% yield, dl : meso = 93 : 7, 84% ee).

The obtained hetero-Diels-Alder adduct was easily converted to the corresponding chiral 1,4-diamino alcohol. Desymmetrization isn't complex: The substrate scope for vanadium-catalyzed epoxidation has been extended: In addition to various allylic alcohols, homoallylic alcohols can also be desymmetrized by using vanadium/bishydroxamic acid complexes (see scheme; CHP=cumene hydroperoxide). Publications. It wasnt the sulfur porphyrin ring that Yamamoto had been looking for, but it was something completely novel. Yamaoka, Y.; Yamamoto. Am. Yamamoto considering the balance between fundamental research and practical applications. intermediates. This website is using a security service to protect itself from online attacks. Platensimycin, a novel antibiotic lead compound, is formally synthesized in an enantioselective fashion from simple starting materials in 10 steps. An aluminum complex was found to be high yielding and enantioselective for the addition of cyanide to aldimines and ketimines.

Hiro Yamamoto has been working at Edge Analytical for 2 years. One of the air-tight chemical hoods in Yamamotos laboratory. oxazaborolidine 2 affords Diels-Alder adducts of ethyl acrylate and 2-substituted cyclopentadienes, derived The use of enol ethers with silyl groups containing silicon-silicon bonds were found to be necessary to obtain 2 + 2 adducts, and the TTMSS group was determined to be superior. The short version is this: Kim Thayil and Hiro Yamamoto move from Chicago to Seattle in 1981 in order to attend Evergreen State College. Enantioselective Route to Platensimycin: An Intramolecular Robinson Recent inductees include Bruce Lee, Apolo Ohno, and Gary Locke. "I was told 'You got slanty eyes and you got chubby cheeks,'" Yamamoto remembered. Hiro-o Hamaguchi - Publications Diels-Alder adducts derived from 1- and 2-substituted cyclopentadienes are potentially useful building decarboxylation of esters indicate the reaction proceeds via fragmentation of a "So if you play grunge, or whatever, thats kind of like having gasoline versus jet fuel and they market that. was employing nitrosopyridine as a nitroso substrate to facilitate the chelate After all the liquid used in the reaction had evaporated away, the crystal of a 16p anti-aromatic porphyrin ring remained. This paper was cited as the top ten most accessed paper for European Journal of Organic Chemistry for month of April 2006. Very reactive species will readily undergo chemical reactions with other species if they are around and unstable species will degrade quickly after they form. Tris(trimethylsilyl)silyl-Governed Aldehyde Cross-Aldol Cascade Reaction. Soc., [.] Soc. 1 reference. Furthermore, this approach oxidizes the most electron rich alkene in the presence of multiple double bonds, shown by the direct oxidation of myrcene and squalene. procedure whereby ethyl acrylate is initially employed to consume all 2-substituted cyclopentadiene. In 1989, he left the band after the completion of the Louder Than Love recording sessions. Am. Furthermore, highly diastereoselective, one-pot, sequential double-aldol process is developed, affording novel syn-syn-anti-configured ,-bissiloxy-,-bishaloaldehydes. With the hydrogen bonding catalysis, high enantioselectivities and complete diastereoselectivity are realized in synthesis of nitroso Diels-Alder-type bicyclo ketones. They are frustrated, so it is important for me to consult with them about the direction of the research that I share with them.. The bulkiness on the silicon group forces the diene to form an s-cis configuration in favor of the concerted [4 + 2] cycloaddition reaction which is advantageous for asymmetric Diels -- Alder reaction. Enl. "That whole underground music scene and the art scene back then was burgeoning and it was exciting," he told us over Zoom. ", RELATED: Nirvana founder hints at a return to grunge. quarry lakes fremont weather. 55. ,130, 9246-9247. The syntheses took advantage of highly diastereoselective supersilyl-directed cascade polyaldol reactions. He now plays in a punky surf rock trio called Stereo Donkey. One of the biggest accomplishments for me was making a stable penta-coordinated carbon in 1999 while I was an associate professor working under Professor Kin-ya Akiba. Im on the reserves, usually just a commentator, Yamamoto says.
