  Abstract A facile synthesis of novel dispiro oxindole-pyrrolothiazole-androsterone hybrid heterocycles has been achieved through 1,3-dipolar cycloaddition. The reaction proceeds stereo- and regioselectively, affording a single isomer of the product in excellent yields with the formation of two C–C and one C–N bonds and creation of four new contiguous stereocenters in one step.
