-
Page/Page column 14; 15, (2010/11/24)
The invention relates to commercially viable process for the preparation of Rosuvastatin by an early introduction of correct absolute stereochemistry at C-5 (S) of Rosuvastatin side chain followed by regioselective chain extension using novel side chain building blocks and less expensive reagents. It is yet another object of the invention is to provide novel intermediates that may be used for the preparation of Calcium salt of Rosuvastatin.Formula (I).
