Publikováno v: Tetrahedron. 56:2821-2831

The diastereoselectivity in the conjugate addition of organocopper reagents to γ-aryl α,β-unsaturated carbonyl derivatives 8–14 was investigated. The syn -diastereoselectivity was obtained irrespective of the reagents type in the addition of 8,

Publikováno v: Glycoconjugate Journal. 15:107-113

The novel glycosphingolipid, SEGLx (Gal beta 1-4(Fuc alpha 1-3)Glc beta 1-3Gal beta Cer), which was identified by us (Kawakami Y, et al. (1993) J Biochem 114: 677-83), shows a characteristic spectrum on 1H-NMR analysis, in which the anomeric proton r
