Thiazolidin-2-one, cas is 2682-49-7, it is a common heterocyclic compound, the thiazolidine compound, its synthesis route is as follows.
Thiazolidinone (3.43 g, 29.32 mmol) and POBr3 (25 g, 87.96 mmol, 3 equiv.) are mixed under nitrogen as solids. The reaction mixture is then heated to HO0C under stirring for 3 h causing the formation of a black syrup. The reaction mixture is then allowed to cool down to room temperature and a mixture of water/ice (200 mL) is added very cautiously. The resulting grey suspension is extracted with diethyl ether (3 x 50 mL), the organic layers are combined, filtered through a silica plug and evaporated to afford the title compound as an orange oil (4 g, 57%) which is used in the next step without further purification., 2682-49-7
With the rapid development of chemical substances, we look forward to future research findings about Thiazolidin-2-one
