    • Note
    • Experimental procedure for synthesize indolizines: pyridine derivative (1, 0.21 mmol) and α-halide carbonyl compound (2, 0.20 mmol) in 0.20 mL of DMF were heated at 60 °C in a test tube with a stopper for 2 h to form 3 in situ. Then alkene (4, 0.30 mmol), potassium dichromate (0.15 mmol) and another 1.80 mL of DMF were added to the tube. Then the mixture was heated at 80 °C for another 8 h (the reaction course was monitored by TLC). Then the mixture was cooled to r.t., passed through a layer of silica gel and washed with ethyl acetate to remove the inorganic by-products. Then solvent was removed by reduce pressure. The residue was purified by flash chromatogram on silica gel using petroleum ether/ethyl acetate as eluate to give the corresponding indolizine.
