Abstract:
A series of rhodol-; fluorescein- and rhodamines-based spirolactam compounds, bearing electron donor amines have been prepared. For this purpose we have redesigned the synthesis of the rhodol scaffold using 2-(2,4-dihydroxybenzoyl)benzoic acid obtaining one example rhodol methyl ester in good yields (25-30 %) Thus, one set of non-cytotoxic rhodamine-based compounds has been prepared using thermal and microwave assisted synthesis (40-78 %) and tested as high affinity ATP chemo-sensors.
