Study on the Synthesis of 2,2-Bibenzyl-4,6-Biphenyl-1,3,5-Trithiane and its Odou

Abstract:

A novel spice, 2,2-bibenzyl-4,6-biphenyl-1,3,5-trithiane, was synthesized using ethanol, 1,3-diphenyl- 2,2-dithiol and FeCl3 as raw materials and p-toluenesulfonic acid as catalyst. The yield of the product was shown to be 63.0% and its structure was characterized by IR, 1H NMR and MS. Besides, the odour of the product was identified, which is similar to onion and garlic fragrance with the thresholds being of 0.2210-6~0.3710-6 mol/L in water and 1210-6~15.3310-6 mol/L in vegetable oil.
