With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.1608-26-0,N,N,N’,N’,N”,N”-Hexamethylphosphinetriamine,as a common compound, the synthetic route is as follows.
General procedure: To a mixture of (S)-3,3′-Dibenzyl-5,5′,6,6′-tetramethyl-1,1′-biphenyl-2,2′-diol24 (0.42 g, 1.00 mmol) in toluene (5 mL) was added hexamethylphosphorous triamide (248 mg, 1.50 mmol) under nitrogen. The resulting mixture was stirred at 80 C for 17 h. The solvent was evaporated under reduced pressure to afford a gel-like product, which was further purified by column chromatography on silica gel (pretreated with 1% NEt3 in hexanes) using hexanes/EtOAc (19/1) as the eluent to give (R)-MPN-Lf (0.32 g, 65%) as a white solid., 1608-26-0
As the paragraph descriping shows that 1608-26-0 is playing an increasingly important role.
