Lead-Catalyzed Aqueous Benzoylation of Carbohydrates with an Acyl Phosphate Ester

Biochemical systems utilize adenylates of amino acids to aminoacylate the 3′-terminal diols of tRNAs. The reactive acyl group of the biological acylation agent is a subset of the general class of acyl phosphate monoesters. Those compounds are relatively stable in aqueous solutions, and their alkyl esters are conveniently prepared. It has previously been shown that biomimetic reactions of acyl phosphate monoesters with diols and carbohydrates are promoted by lanthanide salts. However, they also promote hydrolysis of acyl phosphate reagents, and the overall yields are modest. An assessment of the catalytic potential of alternative Lewis acids reveals that lead ions may be more effective as catalysts than lanthanides. Treatment of carbohydrates with benzoyl methyl phosphate (BMP) and triethylamine in water with added lead nitrate produces monobenzoyl esters in up to 75% yield. This provides a water-compatible pathway for novel patterns of benzoylation of polyhydroxylic compounds.

Regioselective benzoylation of diols and carbohydrates by catalytic amounts of organobase

A novel metal-free organobase-catalyzed regioselective benzoylation of diols and carbohydrates has been developed. Treatment of diol and carbohydrate substrates with 1.1 equiv. of 1-benzoylimidazole and 0.2 equiv. of 1,8-diazabicyclo[5.4.0]undec-7-ene (DB

Magnesium ion enhances lanthanum-promoted monobenzoylation of a monosaccharide in water

Magnesium ion combines selectively with the methyl phosphate by-product in the lanthanum-promoted biomimetic reaction of benzoyl methyl phosphate with monosaccharides.

Chelation-controlled regioselectivity in the lanthanum-promoted monobenzoylation of monosaccharides in water

Monosaccharides are selectively converted to monobenzoates in a base-catalyzed reaction with benzoyl methyl phosphate (BzMP) and a lanthanum salt in water. Yields are reported in terms of formation of the ester, which competes with hydrolysis of BzMP, to

Lanthanum-catalyzed aqueous acylation of monosaccharides by benzoyl methyl phosphate

It was previously reported that diols dissolved in water (pH 8, EPPS buffer) react with benzoyl methyl phosphate (BMP) in the presence of lanthanide ions to form monobenzoyl esters. We have investigated the possibility of extending this process to include

A new highly regioselective reaction of unprotected sugars for chemical synthesis of 6-acyl-D-glycopyranosides

New methodologies developed to synthesize 6-acyl-D-glycopyranosides are described. Thus, regioselective acylation of non protected glycopyranosides was performed using acyl-p-nitrothiophenol esters and acyl-2,4-dinitrophenol esters as the acylating reagen

Regioselective Monoacylation of Some Glycopyranosides via Cyclic Tin Intermediates

Selective mono-benzoylation of some pento- and hexo-pyranosides (Me β-L-Ara, Ph α-L-Ara, Me α-D-Xyl, Me β-D-Xyl, Me α-D-Glc, Me-β-D-Glc, Me α-D-Gal, Me β-D-Gal, and Me α-D-Man) by using Bu2SnO was examined in comparaison with the results of the (Bu3Sn)2O method and direct benzoylation.The Bu2SnO method is particularly useful in that it selectively activates an equatorial hydroxyl group wich bears an oxygenated function (OH or OMe) in a cis relationship at an adjacent position, even in the presence of a more reactive primary OH group.The various mono- and di-O-benzoyl derivatives prepared in this work were unambiguously identified by analysis of their 13C-nuclear magnetic resonance spectra.
