Leshch, Yevgeniy,Jacobsen, Anna,Thimm, Julian,Thiem, Joachim
supporting information, p. 4948 - 4951 (2013/10/22)
Novel monoketoheptuloses have been synthesized employing an amination step in a pre- and/or post-C1 chain elongation using a Petasis reagent by starting from aldohexoses or aldohexosamines. A series of gluco and manno configured 1-/3-deoxy-1-/3-amino-keto
Highly efficient synthesis of ketoheptoses
Waschke, Daniel,Thimm, Julian,Thiem, Joachim
, p. 3628 - 3631 (2011/09/15)
A reliable, facile, high overall yielding and diastereoselective synthesis of ketoheptoses was developed and applied for preparation of the two most diabetogenic ketoheptoses as well as in a modified version for the synthesis of kamusol.

We report the synthesis of spiro-sulfamidate glycosides from exo-glycals. This route is regioselective and furnishes an original class of spiro-hydantoin glycoside analogues. A biological evaluation of this family on a range of glycosidases shows that these compounds are weak but very selective inhibitors of α-glucosidase and amyloglucosidase.
A Ramberg-Baecklund approach to the synthesis of C-glycosides, C-linked disaccharides, and C-glycosyl amino acids
Paterson, Duncan E.,Griffin, Frank K.,Alcaraz, Marie-Lyne,Taylor, Richard J. K.
, p. 1323 - 1336 (2007/10/03)
Synthetic applications of exo-glycals, derived from S-glycoside dioxides using the Meyers variant of the Ramberg-Baecklund rearrangement, are described. These include a formal synthesis of a β-glycosidase inhibitor 12 and an efficient route to spirocyclic glucose derivatives 17 and 18. The synthesis of C-linked disaccharides 24, 31, and 38 and the C-glycosyl amino acid 49 using the Ramberg-Baecklund rearrangement is also reported.

Stereoselective synthesis and structure elucidation of spiro-ketodisaccharides
Li, Xiaoliu,Takahashi, Hideyo,Ohtake, Hiro,Shiro, Moto,Ikegami, Shiro
, p. 8053 - 8066 (2007/10/03)
Cycloglycosylation of 3,4,5,7-tetra-O-benzyl-α-D-hept-2-ulopyranoses (2a-c) was carried out stereoselectively under the catalysis of Lewis acid to afford two spiro-cyclodisaccharides 3a-c and 4a-c in good yields. The reaction provided the kinetic products 3a-c or the thermodynamic products 4a-c as the predominant products under different conditions, respectively. The unprotected disaccharides 5a-c and 6a-c and the acetylated derivatives 7a-c and 8a-c were prepared by catalytic hydrogenation and followed by acetylation. The structures of compounds 4a-c, 6a-c and 8a-c were confirmed to be α,β-anomeric configuration with chair-chair-chair form for the tri-cycles based on the X-ray crystallographic analysis of 6a-c. The α,α-anomeric configurations of compounds 3a-c, 5a-c and 7a-c were determined based on the measurements of the three bond coupling constants 3JC,H between the C-1 and the H-3 of 7a-c.
Synthetic applications of Ramberg-Backlund derived exo-glycals
Alcaraz, Marie-Lyne,Griffin, Frank K.,Paterson, Duncan E.,Taylor, Richard J. K.
, p. 8183 - 8186 (2007/10/03)
Synthetic applications of the title glycals, prepared from S-glycoside dioxides using the Meyers' variant of the Ramberg-Backlund rearrangement are described. These include a formal total synthesis of a novel β-glycosidase inhibitor, and an efficient route to spirocyclic glucose derivatives. In addition, silyl methodology has been developed which allows unprotected exo- glycals to be synthesised.
