We envisioned that PhLi could be replaced by n-BuLi, avoiding therefore the formation of inseparable molecule 4, n-BuLi being more basic, yet less nucleophilic than PhLi. Preventing the formation of 5 was achieved by switching to toluene as solvent to precipitate LiBr formed during the cyclization process, therefore inhibiting its undesired reactivity with 2. With a new set of conditions in hands, products 3a-i were isolated without byproducts in 51-73% yields, upon addition of electrophiles like TsCl and Boc2O or through simple hydrolysis. Importantly, the unprecedented nucleophilic addition of aryl-Grignard reagents onto ABB proved efficient, with a smooth introduction of aryl moieties at position 3. We envisioned that the intermediate magnesium amide 6 resulting from a ring opening reaction could be used in situ in a further nucleophilic aromatic substitution onto electron-deficient aromatics, providing a first approach to bis-arylated structures. 2-Fluorinated pyridines were chosen as appropriate substrates for this transformation, given that their electron-deficient nature allow for the stabilization of the intermediate Meisenheimer complex. After successful generation of the N-azetidinyl-magnesium species 6a in situ -with PhMgBr -further SNAr was performed in the presence of triethylamine and an excess of the electrophilic 2-fluoropyridine to give 7a in 80% yield. Varying the substitution pattern of 2-fluoropyridines yielded halogenated compounds 7b and 7c, nitrile derivative 7d, and 2-fluoroquinoline gave 7e in 70% yield. Electron-rich (p-OMe, p-SR) and electron-poor (p-F) aryl-Grignard reagents were also proven efficient in this transformation, furnishing 7f-h in 40 to 72% yield. The introduction of heteroaromatic was also exemplified with 2thiophenylmagensium reagents, providing 7i (65%).
