A convenient, simple, and high-yielding five-step synthesis of a sphingosine acceptor from phytosphingosine is reported, and its behavior in glycosylation reactions is described. Different synthetic paths to sphingosine acceptors using tetrachlorophthalimide as a protecting group for the sphingosine amino function and different glycosylation methods have been explored. Among the acceptors tested, the easiest accessible acceptor, unprotected on the two hydroxyl groups in positions 1 and 3, was regioselectively glycosylated on the primary position, the regioselectivity depending on the donor used.

scheme or table, p. 2609 - 2612 (2010/02/28)
The synthesis and some examples of glycosylations of a properly protected sphingosine is presented. This compound is suitable for the preparation of glycosphingolipids. It has been used for the synthesis of -mannosylceramide and sulfatide exploiting the anchimeric assistance to address the stereochemistry of the glycosidic bond.

Page/Page column 29-30, (2008/12/04)
The present invention provides a one-pot method of preparing an unprotected α-O-glycolipid. The first step involves contacting a protected α-iodo sugar with a catalyst and a lipid comprising a hydroxy group, under conditions sufficient to prepare a protected α- O-glycolipid. The second step involves deprotecting the protected α-O-glycolipid under conditions sufficient to prepare the unprotected α-O-glycolipid, wherein the contacting and deprotecting steps are performed in a single vessel. The present invention also provides a one-pot method of preparing an unprotected β-O-glycolipid following the steps for the preparation of the unprotected α-O-glycolipid.

, p. 1856 - 1857 (2007/10/03)
A facile synthesis of a combinatorial ceramide library and their activities in the NF-κB pathway and in apoptosis induction/prevention were demonstrated. A novel NF-κB activating molecule was discovered among ceramide containing β-galactose, and the structural requirements of ceramides for apoptosis induction was elucidated. Copyright
