Synthesis of N-Substituted 3-Trifluoroacetyl Pyrroles 5, General Procedure To a solution of 3-trifluoroacetyl-4,5-dihydrofuran 1 (0.50 g, 3.0 mmol) in CH2Cl2 (5 mL, amines 2a,b (approx. 6.0 mmol, amines 2c-r (3.0 mmol, and amines 2s-u (1.5 mmol) were added under magnetic stirring, and the reaction was stirred for 30 min at r.t. After this period, PCC (4.5 mmol) in CH2Cl2 (5 mL) was added, and the reaction mixture was refluxed for 3 h. For amines 2a,b, before the addition of PCC, the reaction was extracted with CH 2Cl2 (3 x 15 mL) and dried with MgSO4. The solvent was evaporated by rotary evaporator, and the reaction residue was treated with 1 M solution of NaOH and extracted with Et2O (3 x 50 mL, The combined organic layers were washed with 1 M NaOH solution (2 x 50 mL) and distilled H2O 1 x 50 mL, The organic phase was dried with anhyd MgS
