Take control! An unprecedented sulfenylation of stereochemically defined 2-deoxyglycosyl lithium species with asymmetric sugar-derived disulfide acceptors enabled the stereoselective synthesis of both α- and β-S-linked 2-deoxyoligosaccharides. Reductive lithiation of 2-deoxyglycosyl phenylsulfides at -78°C provides predominantly axial glycosyl lithium species, which upon warming isomerize to predominantly equatorial lithium species (see scheme).

Halichoblelides B and C, potent cytotoxic macrolides from a Streptomyces species separated from a marine fish
Yamada, Takeshi,Kikuchi, Takashi,Tanaka, Reiko,Numata, Atsushi
supporting information; experimental part, p. 2842 - 2846 (2012/07/28)
Halichoblelide B (1) and C (2), novel macrolides with potent cytotoxicity against tumor cells in culture, have been isolated from a strain of Streptomyces hygroscopicus originally derived from the marine fish Halichoeres bleekeri, and their absolute stereostructures have been elucidated on the basis of spectroscopic analyses using 1D and 2D NMR techniques and chemical transformations. These compounds exhibited significant cytotoxicity against human cancer cell lines.
Bromodimethylsulfonium bromide catalyzed synthesis of methyl 2-dexoy-4,6-o-benzylidene galactopyranoside from galactal and the rapid route to 2,3- and 2,6-dideoxygalactopyranoses

4,6-O-Benzylidenation of D-galactal with PhCH(OCH3)2 catalyzed by bromodimethylsulfonium bromide leads to methyl 2-dexoy-4,6-O- benzylidene galactopyranoside efficiently, which serves as a key intermediate to the ready preparation of
