Evaluation of thioglycosides of Kdo as glycosyl donors
Mannerstedt, Karin,Ekeloef, Kerstin,Oscarson, Stefan
, p. 631 - 637 (2008/03/13)
The use of Kdo thioglycosides as glycosyl donors using DMTST, IBr/AgOTf and NIS/AgOTf as promoters has been evaluated. Activation at low temperature allowed to escape the formation of 2,3-glycal byproducts to give glycosides in high yield and with good β-
