Chiral beta – amino derivatives of the preparation method (by machine translation)
The invention belongs to the technical field of chemical synthesis, in particular to a chiral beta – amino derivatives of the preparation method. The chiral beta – amino derivatives of the preparation method, comprises the following steps: providing a formula I indicated by the azetidine quaternary ammonium salt, shown as formula II of the nucleophiles; will of the said heterocyclic butane quaternary ammonium salt and the nucleophiles soluble in the organic solvent in the 1st, in alkali and formula III shown under the condition of the catalyst of the asymmetric ring-opening reaction, shown as formula IV obtained chiral beta – amino derivatives. This invention adopts the chiral phosphate chiral catalyst, can be effective to form a chiral phosphorus acid salt, promote the reaction system the occurrence of ion exchange, and then high-efficiency, high selectively to get chiral beta – amino derivative product. Therefore, the preparation method is not merely the reaction condition is simple and easy to control, but also selectively high, to obtain high purity of product. (by machine translation)
