Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 39093-93-1, name is Thiomorpholine 1,1-dioxide. A new synthetic method of this compound is introduced below. 39093-93-1

tert-Butyl thiomorpholine-4-carboxylate (1.91 g, 9.42 mmol) was dissolved in dichloromethane (50 ml); m-chloroperbenzoic acid (5.0 g, 19 mmol) was gradually added while cooled with ice bath, stirred, and under nitrogen atmosphere; and the reaction mixture was stirred at room temperature for 12 hours. After addition of a saturated aqueous solution of sodium thiosulfate, the reaction mixture was kept stirred for a while; and this was subjected to extraction with ethyl acetate, washed with brine, dried over anhydrous sodium sulfate, and concentrated under reduced pressure. Triethylamine (8.1 ml, 58 mmol) were added to the obtained crystals; and the reaction mixture was stirred at room temperature. tert-Butoxycarbonyl dicarbonate (13.3 ml, 58 mmol) was added thereto; and the reaction mixture was stirred at room temperature for 10 hours. The reaction mixture was concentrated under reduced pressure; and the obtained crystals were suspended with a solvent mixture of diethyl ether: ethanol = 10: 1, filtered off, washed with diethyl ether and dried under aeration to yield the title compound as colorless crystals (2.03 g, 8.63 mmol, 91.6percent). 1H-NMR Spectrum (DMSO-d6) delta (ppm): 1.40 (9H, s), 3.09 (4H, t, J=5.2 Hz), 3.72 (4H, t, J=5.2 Hz).

As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. Thiomorpholin-3-one, cas is 20196-21-8,the Thiomorpholine compound, it is a common compound, a new synthetic route is introduced below.

Preparation 6 4-Benzylthiomorpholin-3-one Under a nitrogen atmosphere in a flame-dried flask, sodium hydride (4.65 g, 0.1 05 mol, 54% oil dispersion) was added to 150 mL of anhydrous dimethylformamide (DMF), and the suspension was cooled to 0 C. Thiomorpholin-3-one (11.7 g, 0.1 mol) was added in portions over 30 minutes with stirring. After gas evolution had stopped (ca. 30 minutes), benzyl chloride (12.1 g, 0.105 mol) in DMF (50 mL) was added and stirring was continued at room temperature overnight. The reaction was then warmed to 80 C. for 15 minutes and cooled. Water (250 mL) was added and the mixture was extracted with chloroform which was dried (MgSO4) and concentrated in vacuo to an oil. The oil was triturated with ethyl ether (Et2O) and cooled by dry ice to give the product, 12.75 g as a solid, m.p. 60-62 C. Recrystallization of 5 g from 100 mL of Et2O gave 3.5 g of pure product, m.p. 62-63 C. along with a second crop of 0.75 g with m.p. 62-63 C.
