Regioselective benzoylation of glycopyranosides by benzoic anhydride in the presence of Cu(CF3COO)2.
Carbohydr. Res. 359 , 111-9, (2012) Benzoylation of methyl and benzyl glycopyranosides by benzoic anhydride in acetonitrile in the presence of copper(II) trifluoroacetate as a promoter has given monobenzoates with a good yield and high regioselectivity. The composition of monobenzoates depended... |

Introduction of a benzoyl group onto 6-chloropurine riboside in aqueous solution and its application to the synthesis of nucleoside derivatives.
Nucleic Acids Symp. Ser. 44 , 103-104, (2000) A benzoyl group was introduced onto the 3'-hydroxyl group of 6-chloropurine riboside by treatment with benzoic anhydride in the presence of a base in aqueous solution. The product (3b) was converted to 9-(2,3-Di-deoxy-2-fluoro-beta-D-threo-pentofuranosyl)aden... |

Derivatization for LC-electrospray ionization-MS: a tool for improving reversed-phase separation and ESI responses of bases, ribosides, and intact nucleotides.
Anal. Chem. 76(10) , 2869-77, (2004) We have developed a method for analyzing polar compounds by reversed-phase LC-ESI-MS following esterification of the analytes' free hydroxyl groups with propionyl or benzoyl acid anhydride. The method was applied to members of the plant hormone group cytokini... |

An effective use of benzoic anhydride and its derivatives for the synthesis of carboxylic esters and lactones: a powerful and convenient mixed anhydride method promoted by basic catalysts.
J. Org. Chem. 69(6) , 1822-30, (2004) Various carboxylic esters are obtained at room temperature in excellent yields with high chemoselectivities from nearly equimolar amounts of carboxylic acids and alcohols using 2-methyl-6-nitrobenzoic anhydride with triethylamine by the promotion of a basic c... |

Ru(II) multinuclear metallosupramolecular rack-type architectures of polytopic hydrazone-based ligands: synthesis, structural features, absorption spectra, redox behavior, and near-infrared luminescence.
Chemistry 16(19) , 5645-60, (2010) A novel class of polytopic hydrazone-based ligands was synthesized. They gave heteroleptic Ru(II) polynuclear rack-like complexes of formula [Ru(n)terpy(n)(bridging molecular strand)](2n+) (terpy=2,2':6',2''-terpyridine). The new rack-like systems can be view... |

Benzoolysis of diacylglycerophosphocholines: dephosphorylation and sequential formation of isomeric reaction products.
J. Lipid Res. 37(6) , 1224-33, (1996) Benzoolysis experiments are reported in which diacylglycerophosphocholine is heated at 100 degrees C with benzoic anhydride for variable periods of time. It is shown that more than 90% of the phospholipid is dephosphorylated after 5 h of heating. Lipid extrac... |

Dephosphorylation and benzoylation reactions occurring in the benzoolysis of diacyl-, alkylacyl-, alk-1-enylacyl-, and acyl-lyso-glycerophosphocholines.
J. Lipid Res. 38(8) , 1680-4, (1997) Series of benzoolysis experiments with 1,2-dipalmitoyl glycerophosphocholine (GPC), 1-palmitoyl-2-lyso GPC, and 1-O-hexadecenyl-2-oleoyl GPC, as well as a few experiments with 1-oleoyl-2-acetyl GPC and 1-O-hexadecyl-2-acetyl GPC are reported. The results are ... |

Mass spectrometric analysis of benzoylated sialooligosaccharides and differentiation of terminal alpha 2-->3 and alpha 2-->6 sialogalactosylated linkages at subpicomole levels.
Anal. Chem. 71(21) , 4969-73, (1999) Perbenzoylated sialooligosaccharides were found to be stable derivatives, giving intense signals during the matrix-assisted laser desorption/ionization (MALDI) mass spectrometric analysis in the positive-ion mode. Terminal Neu5NAc alpha 2-->3 and alpha 2-->6G... |

Milk oligosaccharide profiles by reversed-phase HPLC of their perbenzoylated derivatives.
Anal. Biochem. 251(1) , 89-97, (1997) Human milk is rich in oligosaccharides, some of which inhibit toxins and pathogens involved in diseases of infants. To investigate qualitative and quantitative individual variation of human milk oligosaccharides, a sensitive method for routine identification ... |
