Synthesis, characterization, biological activity of novel 1h-benzo[f]-chromene and 12h-benzo[f]chromeno[2,3-d]pyrimidine derivatives
Abd El-Mawgoud, Heba K.,Radwan, Hebat Allah M.,El-Mariah, Fatma,El-Agrody, Ahmed M.
, p. 857 - 865 (2018/07/03)
Background: Chromene, benzochromene and their derivatives have been considered as an important class of oxygen-containing heterocycles. There has been increasing interest in the study of chromenes and benzochromenes due to their biological and pharmacolog
Multi-component synthesis of 2-amino-4h-chromenes catalyzed by nano zno in water
Hosseini-Sarvari, Mona,Shafiee-Haghighi, Sara
experimental part, p. 1285 - 1298 (2012/04/04)
Naphthalenediols, 1-and 2-naphthols, and phenols in the presence of nano ZnO as catalyst and water as green solvent react with methylenemalononitrile, generated in situ from aldehyde and malononitrile, to yield 2-amino-4H- chromenes.
Microwave-assisted one-pot synthesis of 2-Amino-2-chromenes using piperazine as a catalyst under solvent-free conditions
Mobinikhaledi, Akbar,Moghanian, Hassan,Sasani, Fatemeh
experimental part, p. 262 - 265 (2011/06/26)
A simple and efficient procedure for the synthesis of substituted 2-amino-2-chromenes employing one-pot three-component condensation reaction of aromatic aldehydes with malononitrile and activated phenols has been developed by using the odorless and easy
Microwave assisted one-pot synthesis of 2-amino-4hchromenes and spiropyrano[2,3-d]pyrimidine
Mahmoud, Alaa F.,Abd El-Latif, Fathy F.,Ahmed, Amira M.
experimental part, p. 91 - 96 (2010/10/02)
A convenient and efficient method using microwave assisted one pot synthesis reactions for synthesis of 4H-benzo[f]chromenes by the reaction of aromatic aldehydes with a mixture of malononitrile and naphthols was examined. The synthesis of spiropyrano[2,3-d]pyrimidines by the reaction of isatin with malononitrile and barbituric acid and/or thiobarbituric acid was investigated. The versatility of the method was also examined through the reaction of aromatic aldehydes and malononitrile with various reagents.
One-step synthesis of substituted 2-amino-4H-chromenes and 2-amino-4H-benzo[f]chromenes. Molecular and crystal structure of 2-amino-3-cyano-6-hydroxy-4-phenyl-4H-benzo[f]chromene
