PROCESS FOR SYNTHESIS OF EZETIMIBE AND INTERMEDIATES USED IN SAID PROCESS

A process for the production of ezetimibe and intermediates used in said process are disclosed. A kind of Morita-Baylis-Hillman adduct can be altered to chiral carboxylic acid derivatives of β-arylamino α-methylene with high activity and selectivity by means of ally lamination reaction, and the above carboxylic acid derivatives of β-arylamino α-methylene can be altered to the chiral intermediates of ezetimibe by means of simple conversion and further synthesized into the chiral drug ezetimibe. The synthesis route introduces chirality through the use of a chiral catalysis method, thereby avoiding the use of the chiral auxiliary oxazolidinone; and the route is economical and eco-friendly.
