  3-O-(D-2-propanoyl-L-alanyl-D-isoglutamine)-D- and -L-glucopyranose were synthesized, in order to clarify the structural requirements for the immunoadjuvant activity of the carbohydrate moiety in N-acetylmuramoyl-L-alanyl-D-isoglutamine. Immunoadjuvant activity of the N-acetylmuramoyl-dipeptide analogs was examined in guinea-pigs.

  The order of reactivity of OH and NH groups of glucosamine hydrochloride (GlcNH(2)(.)HCl) and N-acetyl glucosamine (GlcNAc) toward benzylation with NaH/BnBr in DMF was investigated. For GlcNH(2)(.)HCl, benzyl groups were introduced in the order of N-Bn > N-Bn-2 > 1-O-Bn > 6-O-Bn > 4-O-Bn > 3-O-Bn; for GlcNAc, benzyl groups were introduced in the order of 1-O-Bn > 6-O-Bn > 4-O-Bn > 3-O-Bn > N-Bn. A range of partially benzylated 2-N,N-dibenzyl glucopyranosides and GlcNAc derivatives were obtained in a single step.
• Formation of 2-Acetamido-2-deoxy-D-glucopyranosidic Linkages via Glycosidation Using a Combination of Two Lewis Acids

  A mixed activation system composed of ytterbium(III) triflate and a catalytic boron trifluoride diethyl etherate complex efficiently promotes the glycosylation of various alcohol acceptors using 2-acetamido-3,4,6-tri-O-benzy1-2-deoxy-alpha-D-glucopyranosyl acetate in dichloromethane at room temperature to afford 2-acetamido-2-deoxy-D-glucopyranosides in good yields with significant formation of the alpha-isomers. Notably, stereoselective glycosylations of phenol derivatives as the acceptors afforded aryl 1,2-cis-alpha-glycosides without the formation of any beta-isomers. This highly stereocontrolled 1,2-cis-alpha-glycosidation was applied to the synthesis of a novel hydroquinone alpha-glycoside.

  We found that a mixed activating system using ytterbium(III) triflate and a catalytic boron trifluoride diethyl etherate complex efficiently promoted glycosidation of the 2-acetamido-3,4,6-tri-O-benzyl-2-deoxy-alpha-D-glucopyranosyl acetate in dichloromethane at room temperature to afford 2-acetamido-2-deoxy-D-glucopyranosides in good yields along with the formation of a considerable amount of alpha-isomers. Glycosylations of the aryl alcohols as the acceptors stereoselectively afforded aryl alpha-glycosides without producing any beta-isomers.
