(2R,3R)-3-O-Benzoyl-N-benzyltartramide1
The title compound, C(18)H(17)NO(6) [systematic name: (2R,3R)-4-benzyl-amino-2-benzo-yloxy-3-hy-droxy-4-oxobutanoic acid], is the first structurally characterized unsymmetrical monoamide-monoacyl tartaric acid derivative. The mol-ecule shows a staggered conformation around the tartramide Csp(3)-Csp(3) bond with trans-oriented carboxyl and amide groups. The mol-ecular conformation is stabilized ...
متن کاملSynthesis and bioactivity of N-benzoyl-N'-[5-(2'-substituted phenyl)-2-furoyl] semicarbazide derivatives.
In order to find novel chitin synthesis inhibitors (CSIs) with good activity, benzoylphenylurea, a typical kind of CSIs, was chosen as the lead compound and 15 novel derivatives containing furan moieties were designed by converting the urea linkage of benzoylphenylureas into a semicarbazide and changing the aniline part into furoyl groups. The title compounds were synthesized by the reaction of...
متن کاملN-Benzoyl-3-nitrobenzenesulfonamide
In the title compound, C(13)H(10)N(2)O(5)S, the dihedral angle between the phenyl and benzene rings is 86.7 (1)°. In the crystal, mol-ecules are linked into zigzag C(4) chains running along the b axis via N-H⋯O hydrogen bonds.
متن کاملBis(N-benzoyl-N-phenylhydroxylaminato-κ2 O,O′)dimethyltin(IV)
The Sn atom in the title compound, [Sn(CH(3))(2)(C(13)H(10)NO(2))(2)], has a highly distorted octa-hedral coordination with the equatorial plane made up of four O atoms from two N-benzoyl-N-phenyl-hydroxy-laminate ligands and the axial positions occupied by two methyl groups. The crystal structure is stabilized by van der Waals inter-actions.
متن کامل3-O-Benzyl-6-O-benzoyl-1,2-O-isopropilidene-5-C-nitromethyl-a-d-glucofuranose
The title compound, C(24)H(27)NO(9), is one of the epimers of the Henry reaction of 3-O-benzyl-6-O-benzoyl-2-O-isopropyl-idene-a-d-glucofuran-5-one with nitro-methane. The conformation of the five membered rings is as expected from the precursor compound and the mol-ecule is folded with a dihedral angle of 51.4 (2)° between the aromatic rings. One O-H⋯O hydrogen bond and some intra-molecular an...
