00925njm 22002777a 4500 dc G. Herraiz, Ana author G. Suero, Marcos author 2019-06-11 We describe the recent emergence of a new approach for the synthesis of cyclopropane rings by means of photoredox catalysis. This methodology relies on the photocatalytic generation of radical carbenoids or carbenoid-like radicals as cyclopropanating species, and its characterized by an excellent functional group tolerance, chemoselectivity and ability to cyclopropane E/Z alkene mixtures with excellent stereocontrol. The mild reaction conditions and the employ of user-friendly reagents are highly attractive features that may find immediate use in academic and industrial laboratories. http://hdl.handle.net/2072/359749 https://doi.org/10.1055/s-0037- 1611872 New alkene cyclopropanation reactions enabled by photoredox catalysis via radical carbenoids
