In the title compound, C(16)H(18)N(4)O(7)S, a synthetic sulfonyl-urea herbicide, there are intra-molecular N-H⋯N and C-H⋯O hydrogen bonds. Inter-molecular N-H⋯O and C-H⋯O hydrogen bonds form centrosymmetric dimers. The dihedral angle between the two rings is 50.00 (15)°.

The title compound, C(18)H(18)O(4)S(2), was synthesized by the reaction of 1,2-dibromo-ethane with methyl thio-salicylate. The complete molecule is generated by crystallographic twofold symmetry: two methyl benzoate units are linked by an -S-(CH(2))(2)-S- bridging chain with a gauche S-CH(2)-CH(2)-S torsion angle [72.88 (16)°]. The two aromatic rings form a dihedral angle of 79.99 (6)°. In the ...

In the title quinazolin-4-one derivative, C(24)H(20)N(2)O(3), both the 4-methyl-benzoate [dihedral angle = 83.90 (9)°] and 2-tolyl [87.88 (9)°] groups are almost orthogonal to the central fused ring system. These aryl groups are oriented towards the quinazolin-4-one-bound methyl group. In the crystal, mol-ecules are connected into a three-dimensional architecture by C-H⋯O, C-H⋯π and π-π [ring c...

The 2,3,4-tri-toluenesulfonate ester derivatives of the methyl pyranosides of l-arabinose, d-ribose, d-lyxose, and d-xylose have been prepared, and their substitution reactions with various nucleophiles have been examined. For arabinose, xylose, and ribose, highly regioselective monosubstitutions were observed with benzoate, nitrite, and azide anions. These reactions have led to short and simpl...

Stephanotis floribunda (Asclepediaceae), a plant that grows in Madagascar and is now a common house plant, emits a number of volatiles from its flowers. Its floral scent has been noted to increase in intensity during the night. At this time prominent scent compounds include benzyl alcohol, benzyl acetate, benzyl benzoate, eugenol, α-farnesene, linalool, linalool oxide, methyl benzoate (MBA), me...
