A sequential one-pot, two-step, three-componentreaction for efficient synthesis of spiro-substituted 1,3-thiazine library has been developed. The syntheses were achieved by reacting cyanoacetamide with isothiocyanate derivatives to give rise to 2-cyano-3-mercaptoacrylamides, which are trapped in situ by various cycloketones through cyclization, providing multifunctionalized spiro-substituted 1,3-thiazine
