Improved method for synthesis of 1, 4-dihydropridine calcium antag-onists with ultrsound

Luo Wenbo ,Zhang SanqiDepartment of Chemistry , Xi’an 710033  
Comparative study of the synthetic reactions of 1,4-dihydropridine-calcium antagonists with thoseof the same reactions by using ultrasound was performed. It was shown that ultrasound can improve the qual-ity and increase the yield of product as well as shorten the reaction time to some extent.
