Assembly of Complex 1,4‐Cycloheptadienes by (4+3) Cycloaddition of Rhodium(II) and Gold(I) Non‐Acceptor Carbenes Armengol-Relats, Helena Mato, Mauro Echavarren, Antonio M. The formal (4+3) cycloaddition of 1,3‐dienes with Rh(II) and Au(I) non‐acceptor vinyl carbenes, generated from vinylcycloheptatrienes or alkoxyenynes, respectively, leads to 1,4‐cycloheptadienes featuring complex and diverse substitution patterns, including natural dyctiopterene C′ and a hydroxylated derivative of carota‐1,4‐diene. A complete mechanistic picture is presented, in which Au(I) and Rh(II) non‐acceptor vinyl carbenes were shown to undergo a vinylcyclopropanation/Cope rearrangement or a direct (4+3) cycloaddition that takes place in a non‐concerted manner. 2021-05-04T09:44:15Z 2024-04-23T10:44:00Z 2021-05-04T09:44:15Z 2024-04-23T10:44:00Z 2021-05-04T09:44:15Z 2024-04-23T10:44:00Z 2020-10-20 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion http://hdl.handle.net/2072/449892 https://doi.org/10.1002/anie.202012092 eng PID2019- 104815GB-I00 CEX2019-000925-S Advanced Grant No. 835080 2017 SGR 1257 info:eu-repo/semantics/openAccess L'accés als continguts d'aquest document queda condicionat a l'acceptació de les condicions d'ús establertes per la següent llicència Creative Commons:http://creativecommons.org/licenses/by-nc-nd/4.0/ RECERCAT (Dipòsit de la Recerca de Catalunya)
