3-Acetyl-1-phenylthiourea
In the crystal structure of title compound, C(9)H(10)N(2)OS, there are two symmetry-independent mol-ecules, each having an intra-molecular N-H⋯O hydrogen bond generating an S(6) ring motif. The benzene rings and the virtually planar acetyl-thoiurea fragments [r.m.s. deviations = 0.0045 and 0.0341 Å] are oriented at dihedral angles of 50.71 (6) and 62.79 (6)° in the two mol-ecules. In the crysta...
متن کامل3-Acetyl-1-(3-methylphenyl)thiourea
In the crystal structure of the title compound, C(10)H(12)N(2)OS, the conformation of the two N-H bonds are anti to each other. The amide C=O and the C=S are are also anti to each other. The N-H bond adjacent to the benzene ring is syn to the m-methyl groups. The dihedral angle between the benzene ring and the side chain [mean plane of atoms C-C(O)N-C-N; maximum deviation 0.029 (2) Å] is 14.30 ...
متن کامل3-Acetyl-1-(3-chlorophenyl)thiourea
In the title compound, C(9)H(9)ClN(2)OS, the 3-chloro-phenyl and acetyl-thio-urea fragments are oriented at a dihedral angle of 62.68 (5)°. An intra-molecular N-H⋯O hydrogen bond generates an S(6) ring motif. Mol-ecules are linked into dimers via a cyclic R(2) (2)(8) motif of N-H⋯S hydrogen bonds. These dimers are further connected through C-H⋯S inter-actions, completing an R(2) (2)(12) motif, ...
متن کاملSynthesis of 3/?-Acetoxy-7a-aza-B-homo-22a-spirost-5(6)-en-7-one
The modification and enhancement of biological activity [1,2] of steroidal drugs containing nitrogen atom represent one of the most fruitful developments in medicinal chemistry. Voluminous literature [3] is available on azasteroids. However, a limited work is reported [4-8] about the preparation of aza derivatives corresponding to steroidal sapogenins. This prompted us to make an attempt in thi...
متن کامل3-Acetyl-1-(2,3-dichlorophenyl)thiourea
In the crystal structure of the title compound, C(9)H(8)Cl(2)N(2)OS, there are two mol-ecules in the asymmetric unit which are connected by a pair of N-H⋯S hydrogen bonds. An intra-molecular N-H⋯O hydrogen bond stabilizes the mol-ecular conformation of each molecule.
