摘要：

An unprecedented atom-economic redox neutral regioselective Rh-(III)-catalyzed cascade [3+2] annulation of 2-aryl oxazoline with alpha,beta-unsaturated nitro olefins has been accomplished, furnishing a novel set of nitro-functionalized indene-tethered amino alcohols through a synergistic ring-closing/ring-opening strategy via the formation of two new C-C bonds and the regioselective cleavage of the C2-O bond of oxazoline under silver free mild reaction conditions with a broad substrate scope.
