ChemInform Abstract: The Use of 2,6-Anhydro-2-thio Sugar for a Highly Stereocontrolled Glycosylation: A Novel Strategy for Synthesis of 2,6-Dideoxy-α- glycosides

Autor: Kazunobu Toshima, Takashi Ishiyama, Satsuki Mukaiyama, Kuniaki Tatsuta

Publikováno v: ChemInform. 22

A novel and efficient synthesis of 2,6-dideoxy-α-glycosides was developed by use of phenyl 2,6-anhydro-1,2-dithio-D-altropyranosides as glycosyl donors in a highly stereocontrolled glycosylation.

ChemInform Abstract: The Selective Distinction of Diethylisopropylsilyl Ether in Hydrogenolysis

Autor: Koji Yanagawa, Kazunobu Toshima, Kuniaki Tatsuta, Satsuki Mukaiyama

Publikováno v: ChemInform. 23

The diethylisopropylsilyl ether was distinguished from t-butyldimethysilyl, t-butyldiphenylsilyl and benzyl ethers with high selectivity in hydrogenolysis by use of Pd(OH)2 as a catalyst.

Highly β-stereoselective glycosylation by use of 1-O-acetyl-2,6-anhydro-2-thio glycosyl donor for synthesis of 2,6-dideoxy-β-glycosides

Autor: Satsuki Mukaiyama, Kuniaki Tatsuta, Yuko Nozaki, Kazunobu Toshima

Publikováno v: Tetrahedron Letters. 33:1491-1494

Gycosylations of the 1-O-acetyl-2,6-anhydro-2-thio sugar 3 with alcohols in the presence of several Lewis acids in CH 2 Cl 2 proceeded smoothly to give the corresponding β-O-glycosides with high stereocontrol in high yields, and the selectivity of t

Application of efficient glycosylation of 2,6-anhydro-2-thio sugar to the total synthesis of erythromycin A

Autor: Satsuki Mukaiyama, Tetsuro Tamai, Kazunobu Toshima, Kuniaki Tatsuta, Takehito Yoshida

Publikováno v: Tetrahedron Letters. 32:6155-6158

The total synthesis of erythromycin A ( I ) from (9S)-9-dihydroerythronolide A (2) was achieved efficiently by the highly stereoselective and powerful glycosylation of 2,6-anhydro-2-thio sugar 9 as a key step.

Publikováno v: Tetrahedron Letters. 32:4139-4142

L-Cladinose ( 1 ) and its C-3 epimer 2 were synthesized through a highly stereoselective addition of methyl anion to the C-3 carbonyl groups of α-anomer 9 and β-anomer 10 having 2,6-anhydro-2-thio structures, respectively, which were prepared from
