Synthesis and Aromatization of Hantzsch 1 , 4 - Dihydropyridines under Microwave Irradiation . An Overview
Domestic microwave ovens as well as laboratory reactors have been successfully employed to prepare dialkyl 1,4-dihydropyridine-3,5-dicarboxylates and to induce the synthesis of the corresponding aromatic derivatives. In that latter particular case, unexpected results have been reported.
متن کاملOxidation of Hantzsch 1,4- Dihydropyridines to Pyridines with Thallium Triacetate
Hantzsch 1, 4-dihydropyridines (1,4-DHPs) can be oxidized to the corresponding pyridine derivatives by thallium triacetate in high yields.
