Abstract The field in dearomatization of aromatic compounds for the construction spirocycle has been developed rapidly over last two decades and it provides alternative synthetic method without using extra stoichiometric amounts chemical oxidants or reductants. In addition, radical cascade reactions alkenes alkynes that produce multiple bonds one‐step are significant direct efficient building complex molecules. By combining these concepts, opens a new powerful avenue accessing These have well explored past decade. As result, we summarize recent eventful advances this growing area as review, which typical examples listed mechanism also discussed. magnified image
