実験手順
The first step in the process for making Justicidin P can be conducted by adding boron trifluoride etherate (BF3.Et2O) to a solution containing 3,4-dimethoxybenzaldehyde and 1,3-propanedithiol in methylene chloride. After a suitable reaction time, the mixture is washed with a NaOH solution and a saturated solution of NaCl. The product is dried and then recovered by evaporation under reduced pressure.
