Two series of new 2,3-dihydrooxazole-spirooxindole derivatives were efficiently synthesized starting from N′-(2-oxoindolin-3-ylidene) benzohydrazide/N′-(2-oxoindolin-3-ylidene)-2-phenoxyacetohydrazide using designed synthetic route. Newly synthesized 2,3-

The transition metal complex of Mn(II), Co(II), Ni(II), Cu(II), Ti(III), Cr(III), Fe(III), Zr(IV), and UO2(VI) ion with a Schiff’s base ligand derived from 2-hydroxy-[2-oxo-1,2-dihydro-3H-indol-3-ylidene]-benzohydrazide have been prepared. The complexes have been characterized by elemental analysis data, IR and electronic absorption spectra, magnetic moments, and thermogravimetric analysis data. The complexes of the 1: 1 metal-to-ligand stoichiometry have been formed. The physico-chemical data have suggested the octahedral geometry for all the complexes except for Cu(II); the Cu(II) complex has been square planar. Thermal analysis data of the ligand and its complexes have been analyzed, and the kinetic parameters have been determined using the Horowitz–Metzger method. According to the solid-state electrical conductivity measurements, the ligand and its complexes are semiconducting in nature. The antimicrobial activity of the ligand and the complexes towards E. coli, S. typhi, P. aeruginosa, and S. aureus has been tested by the disc diffusion method.
Transformation of isatin 3-acylhydrazones under acetylating conditions: Synthesis and structure elucidation of 1,5′-disubstituted 3′-acetylspiro[oxindole-3,2′-[1,3,4]oxadiazolines]

Several substituted isatin 3-acylhydrazones (e.g. 1a-k, n, p, t) have been synthesized. Under acetylating conditions they were transformed into selectively acetylated derivatives (e.g., 1l, n, o, q-s) and into the novel, title spiroheterocycles (2a-i). Some side reactions occurring under various acetylating conditions are also discussed.
