Synthesis of Thieno[3,2-b]thiophenes from 2,5-Dicarbonyl 3-Nitrothiophenes via Nucleophilic Aromatic Substitution of the Nitro Group with Thiolates
Roman A. Irgashev & Nikita A. Kazin · Organics · 2024
In this study, we developed an efficient strategy for constructing thieno[3,2-b]thiophene molecules from 3-nitrothiophenes, containing carbonyl fragments at the C-2 and C-5 atoms, by nucleophilic aromatic substitution of the nitro group in these substrates. It was shown that the...
