Yield	Reaction Conditions	Operation in experiment
1.45 g	With aluminum (III) chloride; In 1,2-dichloro-ethane; at 25℃;Reflux;	Synthesis of 3: A chloroform solution of 2 (2.00 g, 12.8 mmol) in the presence of a catalytic amount of DMF (0.05 mL) was treated dropwise with thionyl chloride (1.86 mL, 25.6 mmol) under a N2 atmosphere at 25 C. The mixture was heated under reflux for 2 hours. The resulting dark orange solution was cooled, and concentrated in vacuo to give a brown oil. A 1,2-dichloroethane (DCE) solution of the carboxylic acid chloride was added dropwise to a suspension of AlCl3 (1.71 g, 12.8 mmol) in DCE at 25 C. The mixture was stirred overnight at 25 C., then heated under reflux for 2 hours, and afterwards poured into an aqueous solution of HCl (5%). The aqueous phase was extracted with CH2Cl2, dried over Na2SO4, and evaporated. The residue was purified with a short silica pad (CH2Cl2) to afford cyclopenta[b]thiophen-6-one 3 as a white solid upon standing (1.45 g, yield: 82%). 1H NMR (400 MHz, CDCl3): delta (ppm)=2.98-3.00 (m, 2H), 3.02-3.04 (m, 2H), 7.05 (d, J=4.8 Hz, 1H), 7.89 (d, J=4.8 Hz, 1H).

Yield	Reaction Conditions	Operation in experiment
30%	With methanesulfonic acid; phosphorus pentoxide; at 20℃; for 1h;	To a suspension of P2O5 (25.4 g, 179.0 mmol) in methanesulfonic acid (100 mL) was added 3-(thiophen-3-yl)propanoic acid (5.0 g, 32.0 mmol) and the reaction was stirred at room temperature for 1 h. At completion, the reaction was concentrated and the residue was purified by flash chromatography (20-30% EtOAc/hexane eluent) to give 4H-cyclopenta[b]thiophen-6(5H)-one (1.34 g, 30% yield) as a brown solid. 1H NMR (300 MHz, MeOH) delta ppm 8.14 (d, J=4.8 Hz, 1H), 7.17 (d, J=4.8 Hz, 1H), 2.94-3.15 (m, 4H); MS (EI) m/z=139.2 [M+1]+.
0.41 g	With phosphorus pentoxide; In methanesulfonic acid; at 20℃; for 1h;	Step iii: 4H-cyclopentarblthiophen-6(5H)-one To a 50 mL round bottom flask, were added phosphorous pentoxide (8.5 g, 0.0299 mol) and methanesulfonic acid (17 mL). To the same flask, 3-(thiophen-3-yl)propanoic acid (0.85 g, 0.0054 mol) was added. The reaction mixture was stirred at RT for 1 h. The reaction mixture was quenched with ice cold water and extracted with ethyl acetate. The organic layer was separated, washed with brine, dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure to get crude product. The crude product was purified by flash column chromatography using 30 % ethyl acetate in hexane to get the title compound [0.41 g, 55 %]. LC-MS: 139.1 [M+H]+.
