In the structure of the title compound (N3MP2MBA), C(15)H(15)NO, the conformation of the N-H bond is anti to the meta-methyl substituent in the aniline ring and that of the C=O bond is syn to the ortho-methyl substituent in the benzoyl ring, while the conformations of the N-H and C=O bonds are anti to each other. The bond parameters in N3MP2MBA are similar to those in 2-methyl-N-phenyl-benzamid...
Benzoyl-protected mercaptoacetyltriglycine, a synthetic precursor used in the preparation of Technetium-99m-mercaptoacetyltriglycine, a radiopharmaceutical for renal tubular function and L-cysteine methylester, a small, non-zwitterionic amino acid derivative, were used as capping agents of gold nanoparticles obtained by borohydride reduction method. The capped gold nanoparticles composites were...
Enantiomerically pure (S)-tributylstannyl[D1]methanol and (R)- and (S)-tributylstannyl[D1]methyl benzoates were Stille-coupled with bromobenzene and benzoyl chloride in 1,4-dioxane and toluene using [(Ph3P)4Pd] or [(Ph3P)2PdCl2] either alone or in combination with CuCN as cocatalyst at temperatures up to 80 °C. The products were found to be enantiomerically pure. (R)- and (S)-N-(tributylstannyl...
Rate constants and activations parameters are reported for solvolyses of p-Z-substituted benzoyl chlorides (1, Z = OMe, Me, H, and Cl) in 97% w/w hexafluoroisopropanol-water (97H). Additional kinetic data are reported for solvolyses in acetic and formic acids. Plots of log k vs. σ(p) in 97H are consistent with previous research showing that a cationic reaction channel is dominant, even for solv...
Three new compounds: 2R,3R-pterosin L 3-O-beta-D-glucopyranoside (1), beta-D-xylopyranosyl(1-->2)-7-O-benzoyl-beta-D-glucopyranoside (2) and 4-O-benzoyl-beta-D-xylo-pyranosyl(1-->2)-7-O-benzoyl-beta-D-glucopyranoside (3), together with nine known compounds, were isolated from the ethyl acetate extract of Pteris ensiformis. 5-[2-Hydroxyethylidene]-2(5H)-furanone (4), which had been synthesized, ...
Chiral inositols (D-chiro-inositol from D-pinitol and L-chiro-inositol from L-quebrachitol) were converted to the 3,4-di-O-benzyl ethers, which were selectively benzoylated to yield the 1,2,5-tri-O-benzoyl-3,4-di-O-benzyl-chiro-inositols. The free hydroxyl group in each derivative was inverted by way of the trifluoromethane sulfonate ester to provide D- and L-1,2,4-tri-O-benzoyl-5,6-di-O-benzyl...
The conformation of the C=O bond in the structure of the title compound, C(14)H(13)NO, is anti to the meta-methyl substituent in the benzoyl ring. The conformations of the N-H and C=O bonds in the amide group are also anti to each other. The asymmetric unit of the structure contains two mol-ecules. The bond parameters are similar to those in N-(phen-yl)benzamide, 2-methyl-N-(phenyl)-benz-amide ...
