Rev., 43, 2904-2915. doi: 10.1039/c4cs00024b0306-0012http://hdl.handle.net/10347/18490This feature review describes the development of catalytic [4+2] and [4+3] cycloadditions of allenes, as efficient and practical methodologies for assembling six and seven-membered cyclic systems. The different methodologies have been classified depending on the type of key reactive intermediate that was proposed in the catalytic cycleeng© The Royal Society of Chemistry 2014journal article10.1039/C4CS00024B1460-4744open access
