A novel, stereoselective approach towards rosuvastatin calcium from the known (S)-homoallylic alcohol has been developed. The synthesis is highlighted by a regio- and stereocontrolled ICl-induced intramolecular cyclization of chiral homoallylic carbonate to deliver the C6-formyl statin side chain with a syn-1,3-diol moiety. An improved synthesis of the rosuvastatin pyrimidine core moiety is also included. Moreover, this methodology is useful in the asymmetric synthesis of structural variants of statins such as pitavastatin calcium and atorvastatin calcium and their related analogs.

Page/Page column 8, (2010/04/23)
The subject of the present invention is a process for the preparation of rosuvastatin by reacting a compound of formula II, by alkalic hydrolysis to give a compound of formula III, thereafter reacting with an organic or inorganic base to form a salt, eliminating the acetonide group and reacting with calcium-chloride in a base. A further subject of the present invention is a compound of formula III and its salts formed by organic or inorganic base.
