Abstract

A novel spiro-pyrrolothiazole derivative bearing a 2-oxindole substituent was synthesized and characterized. The compound was prepared via a catalyst-free reaction under mild conditions and isolated using a straightforward workup procedure. The structure of the synthesized title compound was confirmed with ¹H, ¹³C NMR spectra and X-Ray diffraction data.

Keywords:

pyrrolothiazoles; 2-oxindole; isatin-β-thiosemicarbazone; thiosemicarbazones; N,S-heterocycles
