3-(2-呋喃甲基)-2-硫氧杂-1,3-噻唑烷-4-

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

实验步骤: To a solution of 2-furaldehyde (43 mL) in hot glacial acetic acid (340 mL) was added rhodanine (68.4 g) and sodium acetate (128.4 g). The solution was refluxed for 0.5 hour and poured into water (2.6 L). The precipitate was collected by filtration and washed with water (1.4 L), ethanol (500 mL), and diethyl ether (200 mL). Recrystallization from acetone gave furfuryl rhodanine (97.4 g). The structure of the product was confirmed by NMR. The solution was refluxed for 0.5 hour The precipitate was collected by filtration washed with water (1.4 L), ethanol (500 mL), and diethyl ether (200 mL) Recrystallization from acetone
