Synthesis of a novel series of 4-O-phosphono-d-glucosamine derivatives (lipid A subunit analogs) carrying the C-branched 2-tetradecylhexadecanoyl group
Abstract A novel series of 4- O -phosphono- d -glucosamine derivatives (lipid A subunitanalogs) carrying the 3- O -linked or 2- N -linked C -branched 2-tetradecylhexadecanoyl group have been synthesized starting from benzyl 2-amino-2-deoxy-4,6- O -isopropylidene-β- d -glucopyranoside and benzyl 2-amino-6- O -benzyloxymethyl-2-deoxy-4- O -(diphenoxyphosphinyl)-β- d -glucopyranoside, respectively.
