The first entry to statins via lactonized side chain is reported, exemplified by the synthesis of rosuvastatin. The key step is Wittig coupling of (2S,4R)-4-(tert-butyldimethylsilyloxy)-6-oxotetrahydro-2H-pyran-2-carbaldehyde and phosphonium salt of an appropriately functionalized pyrimidine heterocy'le. One-pot deprotection and hydrolysis of the resulting 4-O-TBS rosuvastatin lactone provided rosuvastatin in high yield.
