3-乙酰基呋喃

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: As in Example 1, Part A, 0.01 mol of 3-acetylfuran can be reacted with 0.02 mol of N,N-dimethylformamide dimethylacetal to produce 3-dimethylamino-1-(3-furyl)-2-propen-1-one.

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A mixture of 50.0 g. of 3-acetylfuran and 60 ml. of N,N-dimethylformamide is heated at reflux temperature for 16 hours. The solvent is removed in vacuo and hexane is added to the residue to give 3-dimethylamino-1-(3-furyl)-2-propen-1-one. A mixture of 0.01 mole of the preceding compound and 0.01 mole of 3-aminopyrazole in glacial acetic acid is refluxed for 8 hours and the solvent removed in vacuo. The residue is purified as described in Example 1 to give the product of the example. A mixture of 50.0 g at reflux temperature for 16 hours The solvent is removed in vacuo and hexane is added to the residue
