    • Representative Experimental Procedure To a mixture of methyl 2-acetamidoacrylate (11j, 57.3 mg, 0.4 mmol, 1 equiv) and CsF (152 mg, 1 mmol, 2.5 equiv) in dry MeCN (2 mL, 0.2 M) was added o-silyl aryltriflate (1, 121 μL, 0.5 mmol, 1.25 equiv) in an oven-dried 4 mL glass vial. The vial was capped under nitrogen and the mixture was stirred at r.t. overnight (ca. 18 h, The reaction mixture was quenched with HCl (1 N) or TFA (154 μL, 2 mmol, 5 equiv) and the solvent was evaporated. The residue was diluted with NaHCO3 (2 mL, 5, and extracted with EtOAc (3 x 1 mL, The combined EtOAc extracts were dried over Na2SO4 and concentrated. The crude product was purified by CombiFlash chromatography (ISCO) on silica gel column using a gradient elution of 30-80% EtOAc-hexanes to afford methyl 1-methylisoquinoline-3-carboxylate (12j) and methyl 7-(acetylamino) bicyclo[4.2.0]octa-1,3,5-triene-7-carboxylate 13j, Methyl
