In order to obtain coumarin derivatives with activities against HIV,six compounds were designed and synthesized by Pechmann condensation reaction.Their structures were confirmed by IR,EA and 1HNMR.
Microwave irradiation can accelerate the rate of the synthesis reaction of ferrocenyl α,β unsaturated ketones by using KF Al 2O 3 as a catalyst. Six fitled compounds were prepared with microware assisted synthesis. ...Microwave irradiation can accelerate the rate of the synthesis reaction of ferrocenyl α,β unsaturated ketones by using KF Al 2O 3 as a catalyst. Six fitled compounds were prepared with microware assisted synthesis. Their structures were characterized by 1H NMR, IR, and elemental analysis.展开更多
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...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.展开更多
