Abstract
AbstractCatalyst‐free synthesis of the isoxazole‐spirooxindole‐tetrahydrothiophene hybrids is reported. Formation of 1,4‐thia‐Michael and intramolecular aldol reactions were observed (instead of 1,6‐thia‐Michael followed by vinylogous Henry reactions) in a regioselective fashion to give new isoxazole‐spirooxindole‐tetrahydrothiophene hybrids with excellent yields.
