硫代环己酮

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

实验步骤: 5.22 g of L-cysteine and 5 g of tetrahydrothiopyranone are suspended in 50 ml of toluene and the suspension is boiled, using a water separator, until the theoretical amount of water has been separated off. When the suspension is cooled, the product separates out as a light yellow precipitate, which is recrystallized from methanol/water to give 6.9 g of light yellow crystals of melting point 196° C. until the theoretical amount of water has been separated off When the suspension is cooled is recrystallized from methanol/water
