title: Synthesis of neo-glycosylated L-alanyl-D-isoglutamine derivatives as potential immunoadjuvants.
abstract: The synthesis is described for muramyl-dipeptide-related amphiphilic analogs, where 1,10-diaminodecane served as a lipophilic C-terminal linker for the preparation of a bidentated L-alanyl-D-isoglutamine derivative and incorporation of aldonic and uronic acids at the N-termini as hydrophilic cores. For the N-acylation steps via lactones, suitable conditions were elaborated to allow for the use of unprotected or minimally protected aldonic and uronic acid lactones, respectively. These procedures may represent a useful general approach for the synthesis of neoglycopeptides.
