Koduri, Ramesh Goud,Pagadala, Ramakanth,Varala, Ravi,Boodida, Satyanarayana
, p. 333 - 337 (2020/09/23)
Sulfated tin oxide (STO) was established as an admirable heterogeneous catalyst for the single-step synthesis of dihydropyridine derivatives via Hantzsch reaction. The synthetic method was mainly used in the presence of STO as a heterogeneous solid cataly

Kang, Li-Qin,Cao, Zhi-Jun,Lei, Ze-Jun
, p. 1125 - 1128 (2016/09/09)
2-Hydroxyethylammonium acetate ionic liquid was found to be an excellent catalyst for the one-pot synthesis of 1,4-dihydropyridine derivatives via Hantzsch reaction of ethyl acetoacetate or acetoacetanilide, ammonium acetate, and various aromatic aldehyde
Zn-VCO3 hydrotalcite: A highly efficient and reusable heterogeneous catalyst for the Hantzsch dihydropyridine reaction
Pagadala, Ramakanth,Maddila, Suresh,Dasireddy, Venkata D.B.C.,Jonnalagadda, Sreekantha B.
, p. 148 - 152 (2014/01/06)
The Zn-VCO3 hydrotalcite was found to be an excellent solid catalyst for the one-pot synthesis of triphenylpyridine-3,5-dicarboxamide via Hantzsch reaction of acetoacetanilide, ammonium hydroxide and various aromatic aldehydes. The combinatoria
Microwave heating in conjunction with UV irradiation: A tool for the oxidation of 1,4-dihydropyridines to pyridines
Kormos, Chad M.,Hull, Rachel M.,Leadbeater, Nicholas E.
experimental part, p. 51 - 57 (2009/07/18)
Microwave heating is used for the preparation of 1,4-dihydropyridines and then, in conjunction with UV irradiation, is used for the efficient oxidation of the 1,4-dihydropyridines to pyridines. The oxidation reactions are performed in a sealed vessel usin
