Abstract

This minireview highlights the scope of 4‐π‐photocyclizations (photoinduced electrocyclizations that involve 4 pi electrons and generate bicyclic cyclobutenes from 1,3‐dienes), including an overview of the historical progressions as well as recent developments. A range of 1,3‐diene substrates is covered, including cycloheptatrienes, tropones, tropolones, cyclic 1,3‐dienes, 2‐pyrones, 2‐pyridones, pyrimidines, 1,2‐dihydropyridines, and 1,2‐dihydro‐pyridazines. The bicyclic cyclobutene products formed through the photocyclizations are highly versatile synthetic intermediates, and examples of the application of these building blocks in the context of synthetic methodology development, natural product synthesis, medicinal chemistry and materials chemistry are featured throughout.
