摘要
A series of ferrocenyl 1,4 dihydropyridines were synthesized with high yields by a one pot cyclocondensation of formylferrocene,β ketoester and urea(or methyl 3 aminocrotonate) on the surface of SiO 2 under microwave irradiation without solvent.All products were characterized by EA,IR, and 1 HNMR.
