Radical cascade cyclizations of o ‐allyloxybenzaldehydes have emerged as a powerful strategy for the synthesis of 3‐substituted chroman‐4‐ones. This minireview summarizes the incorporation of various functional groups into the C3‐position of chroman‐4‐ones by employing appropriate radical precursors through transition‐metal‐free systems, silver‐catalyzed systems, or visible‐light‐promoted systems.
