Reference of 875444-08-9, Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. 875444-08-9, Name is (4S,5R)-5-(3,5-Bis(trifluoromethyl)phenyl)-4-methyloxazolidin-2-one,introducing its new discovery.
A kind of optical pure aromatic hydrocarbon process for the preparation of beta-amino alcohol (by machine translation)
The present invention discloses an optical pure aromatic hydrocarbon process for the preparation of beta-amino alcohol, which is characterized by comprising the following steps: D or L-amino acid with the starting materials or chloroformic acid benzyl ester CBz-Cl bitter wine acid reaction to obtain compound I-1 BOC; I-1 the compound with paraformaldehyde in a solvent reflux dehydration obtained compound in A I-2; compound I-2 yu Geshi reagent reaction, dilute hydrochloric acid treatment to obtain compound I-3; compound I-3 used can be aluminum isopropoxide catalytic reduction. The purpose of this invention is to overcome the shortcomings of the prior art, to provide a cheap and easily obtained materials to help to reduce the, simple preparation process, the resulting intermediate structure is stable process for the preparation of pharmaceutical intermediates.
