A simple synthetic protocol was developed for the efficient synthesis of functionalized dispiro[indoline-3,1'-cyclobutane-2', 3 ''-indolines] with high diastereoselectivity. The reaction proceeds by cyclodimerization reaction of 3-phenacylideneoxindoles in the presence of a catalytic amount of photosensitizer Ru( bpy(3))Cl-2 and visible light.
