spiro[indoline-3,6’-[1,3]thiazines] were synthesized in modest yields by refluxing of substituted (1,2-dihydroquinolin-3-yl)-methylene)hydrazinecarbothioamides with 2-(2-oxoindolin-3-ylidene)malononitrile in pyridine as a solvent. The structure assignment of all obtained products has been confirmed by 1H, 13C NMR, 2D-NMR, 15N NMR spectroscopy in addition to elemental analyses. The possible mechanism for the
