Fast oxidation of thioglycosides to glycosyl sulfones using KMnO 4/CuSO4·5H2O under neutral reaction conditions
Agnihotri, Geetanjali,Misra, Anup Kumar
, p. 275 - 280 (2007/10/03)
A rapid oxidation of thioglycosides to glycosyl sulfones has been achieved using a combination of KMnO4 and CuSO4·5H 2O in acetonitrile and water. This reaction protocol has many advantages compared to other methods availa
Synthesis of C-glycopyranosyl compounds by a palladium-catalyzed coupling reaction of 1-tributylstannyl-D-glucals with organic halides
Dubois, Eric,Beau, Jean-Marie
, p. 103 - 120 (2007/10/02)
1-Tributylstannyl-D-glucals, prepared from the corresponding 1-phenylsulfonyl-D-glucals, were coupled efficiently to various organic halides in the presence of a palladium(0) catalyst.This mild reaction is specially useful for the preparation of 1-C-aryl-
A Convenient Synthesis of Pyranoid Ene Lactones from Phenyl Glycosyl Sulfones
Qiu, Dongxu,Schmidt, Richard R.
, p. 875 - 877 (2007/10/02)
O-Benzyl protected pyranoid ene lactones (5,6-dihydro-2H-pyran-2-ones) 4a-c, 8 were obtained in high yield in a two-step procedure.Treatment of the phenyl glycosyl sulfones 2a-d, 6, which were readily prepared from their corresponding sulfides, with lithi
PREPARATION AND USE OF LITHIATED GLYCALS: VINYLIC DEPROTONATION VERSUS TIN-LITHIUM EXCHANGE FROM 1-TRIBUTYLSTANNYL GLYCALS
Lesimple, Patrick,Beau, Jean-Marie,Jaurand, Guy,Sinay, Pierre
, p. 6201 - 6204 (2007/10/02)
Methods for preparing glycals lithiated at the C-1 atom by either direct vinylic deprotonation or by tin-lithium exchange from the corresponding 1-tri-n-butylstannyl glycals are described.Alkylation of these lithiated anions wih various electrophiles lead
