Abstract
Abstract Spiro[(2-amino-3-R-6-ethyl-4,6-dihydropyrano[3,2-c][2,1]benzothiazine-5,5-dioxide)-4,3′-(1′-R′-5′-R″-indolin-2′-one)] compounds were synthesized based on the three-component interaction of benzo[c][2,1]thiazin-4-on 2,2-dioxide with corresponding isatins and appropriate methylene active nitriles in the presence of a base as a catalyst. The molecular structures of the target compounds were proved uniquely by the X-ray diffraction analysis method.
