Related Products of 14187-32-7, Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.14187-32-7, Name is Dibenzo-18-crown-6, molecular formula is C20H24O6. In a patent, introducing its new discovery.
The invention relates to a chiral resolution method for preparing a high-purity single-configuration bright ammonia alcohol, which comprises a) and (1). R, 2R- 1, (). C) ethyl acetate is dissolved in ethanol/water mixed solution, dissolved in ethanol/water mixed solution in a plurality of steps, and mixed with a chiral resolving agent and cupric chloride in a molar amount such as ethanol/water b) depressurized rotary evaporation to remove ethanol, ee values of the mixed solution, d) step c and extraction, with ethyl acetate. cyclohexane diamine as precursor, and extraction, concentration of filtrate, and the like in a single configuration of bright ammonia alcohol, and extraction with ethyl acetate. 2 – 98.0% The filtrate, which gave an optically pure levorotatory amino alcohol, ee had a ee value of at 99.0% or aboveThe method has the beneficial effects of simple synthesis method, high chiral resolution yield, high optical purity, and easiness for large-scale chiral resolution.
