Abstract A straightforward and general approach for the stereoselective synthesis of spiro- fused (C-5) isoxazolino-or (C-3) pyrazolino-(C-3) quinolin-2-ones from the adducts offorded from the Baylis–Hillman reaction of 2-nitrobenzaldehyde and ethyl acrylate by sequential 1, 3-dipolar cycloaddition and reductive cyclization is presented. It was found that the reductive cyclization of the isoxazoline derivatives proceeded efficiently in the presence of In/HCl, ...
