The yield of Blaise reaction of trimethylsilyl protected(S)-4-chloro-3-hydroxylbutyronitrile with tert-butyl bromo zinc acetate is improved nearly 20% by using Cu+ or I2 as a single catalyst.Interestingly,when Cu+ and I2 were used as the co-catalyst,the reaction yield was further improved from 72.1% to 97.0%.These results,which were reasonably explained via the reaction mechanism,not only indicate that the Blaise reaction can be applied more widely,but also provide a simple route for the preparation of the side chain of rosuvastatin and atorvastatin.Moreover,this optimized Blaise reaction provides a new insight into the C-C bond formation.

Key words: Blaise reaction, catalyst, side chain of rosuvastatin
