Diastereoselective synthesis of dispiro[indoline-3,1′-cyclobutane-2′,3″-indolines] via visible light catalyzed cyclodimerization of 3-phenacylideneoxindoles
摘要：
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(bpy3)Cl2and visible light.
