23190-16-1, (1R,2S)-2-Amino-1,2-diphenylethanol is a chiral-catalyst compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Example 9; (67?,7?S)-te^-butyl-7-(ter/-butoxycarbonylamino)-8-oxo-3-(trifluoromethylsulfonyloxy)- 1 -aza-bicyclo[4.2.0]oct-2-ene-2-carboxylate; DMF ‘ Step 1 : A mixture of (17?,25)-2-amino-l ,2-diphenylethanol (4.28 g, 20.0 mmol), K2CO3 (0.28 g 2.03 mmol) and diethyl carbonate (20 niL, 166 mmol) was heated under reflux for 16 hrs. The resulting mixture was washed with water (10 mL) and extracted with CH2Cl2 (300 mL). The organic phase was dried MgSO4, filtered and concentrated. The residue was recrystallized form toluene to give the desired compound (4S,5i?)-4,5-diphenyioxazolidin-2-one as white solid. Yield 88%, ESI-MS: 240.1 [M+]
23190-16-1, As the paragraph descriping shows that 23190-16-1 is playing an increasingly important role.
