Abstract: The consecutive alkylation of 9-isopropyl-6-phenyl-9H-purine with methyl 2-diazo-3,3,3-trifluoropropionate and diethyl diazomalonate proceeds at the phenyl substituent firstly via ortho-C–H activation under chelation-assistance of the purine core, followed by classical electrophilic metal carbenoid insertion to the C−H bond of a malonate moiety.

Keywords: carbenoids, C–H functionalization, diazo compounds, organofluorine compounds, homogeneous catalysis, nitrogen heterocycles, purines.
