Abstract
Condensation of 4-amino-3-melthyl-5-styryIisoxazoles 1 with different isatins 2 gives 3(3-methyl-5-styryl-4-isoxazolylimino)-2-indolinones 3. Cyclocondensation of 3 with mercaptoacetic acid and chloroacetyl chloride affords spiro thiazolidinones 4 and spiroazetidinones 5 respectively, while cycloaddition of 3 with benzo nitrileoxide leads to spiro 1,2,4-oxadiazolines 6. The structures of the compounds 3-6 have been established on the basis of their elemental analyses and spectral (IR, 'H NMR and mass) data.
