In the title compound, C(21)H(23)N(3)O(2), the indolin-2-one group is essentially planar, with a maximum deviation of 0.016 (2) Å for the N atom, and makes a dihedral angle of 84.38 (14)° with the benzene ring. The =N-N(H)-C(=O)-C- torsion angle is 0.9 (3)°. In the crystal, mol-ecules are linked into a three-dimensional network via N-H⋯O and C-H⋯O hydrogen bonds. In addition, a C-H⋯π inter-acti...

In the title compound, C(20)H(21)NO(2), the benzyl group and the oxazolidin-2-one unit are each essentially planar, with maximum deviations of 0.026 (2) and 0.031 (2) Å, respectively. The dihedral angle between the phenyl ring and the oxazolidin-2-one unit is 69.25 (2)°. In the crystal, mol-ecules are linked by weak inter-molecular C-H⋯O and C-H⋯π inter-actions.

African history and world history each became substantial fields of historical study in the aftermath of the Second World War. African history organized rapidly in the 1950s and 1960s, an era dominated by modernization-thinking. World history developed slowly until the 1990s, then quickly expanded and generated institutional homes in a time of globalization-thinking. This piece considers issues...
