Strain Release Chemistry of Photogenerated Small-Ring-Intermediates.

Strain Release Chemistry of Photogenerated Small-Ring-Intermediates. Chemistry. 2020 Oct 20;: Authors: Luque A, Paternoga J, Opatz T Abstract Photochemical processes such as isomerizations and cycloadditions have proven to be very useful in the construction of highly strained molecular frameworks. Photoinduced ring-strain enables subsequent exergonic reactions which do not require the input of additional chemical energy as well as a variety of attractive synthetic options leading to complex structures. This review covers the progress achieved in the application of sequences combining excitation by ultraviolet light to form strained intermediates, which are further transformed to lower energy products in strain-release reactions. As ring strain is considerable in small ring systems, photogenerated three- and four-membered rings will be covered focusing on examples from 2000 through May 2020.
