Autor: Kaho Miyazaki, Ryoka Tashiro, Hiroaki Shimada, Hiroto Yasui, Hiroaki Kusano, Rintaro Suzuki, You Ohkubo, Hiroshi Teramura

Publikováno v: Plant Biotechnol (Tokyo)

Late embryogenesis abundant protein (LEA) genes are widely conserved in seed plant species and form a multigene family. While some LEAs are known to respond to environmental stresses, the function of many LEAs is unknown. OsLEA5 (Lea14A) interacts wi

Silylcupration and Copper-Catalyzed Carbomagnesiation of Ynamides: Application to Aza-Claisen Rearrangement

Autor: Hiroto Yasui, Hideki Yorimitsu, Koichiro Oshima

Publikováno v: Bulletin of the Chemical Society of Japan. 81:373-379

Treatment of ynamides with silylcopper reagents resulted in silylcupration to afford (E)-β-silylenamides, after protonolysis, in good yields with high regio- and stereoselectivity. Reaction of ynam...

Cobalt- and rhodium-catalyzed cross-coupling reaction of allylic ethers and halides with organometallic reagents

Autor: Keiya Mizutani, Hideki Yorimitsu, Hiroto Yasui, Koichiro Oshima

Publikováno v: TETRAHEDRON. 62(7):1410-1415

Reactions of 2-alkenyl methyl ether with phenyl, trimethylsilylmethyl, and allyl Grignard reagents in the presence of cobalt(II) complexes are discussed. The success of the reactions heavily depends on the combination of the substrate, ligand, and Gr

Cobalt-catalyzed allylzincations of internal alkynes

Autor: Koichiro Oshima, Toshihiro Nishikawa, Hiroto Yasui, Hideki Yorimitsu

Publikováno v: BULLETIN OF THE CHEMICAL SOCIETY OF JAPAN. 79(8):1271-1274

Cobalt salts such as cobalt(II) chloride catalyze allylzincation reactions of 1-aryl-1-alkynes. The allylzincations proceed in a syn fashion to form 2-allyl-1-aryl-1-alkenylzinc species. Other inte...
