In this work a straightforward visible-light-promoted oxidation of aminohelicenes providing helical ortho-diketones is described [4]. The mechanism of the transformation was studied, showing the reaction likely proceeds via [2+2]-cycloaddition reaction with singlet oxygen as an oxidizer and the reaction is specific to distorted aromatic systems. The diketones represent a versatile material for further transformation, ranging from formation of simple heterocycles bearing helicene moiety, to preparation of very complex nanographene molecules containing multiple helicene parts in their structure.
