Synthesis of some novel benzimidazole derivatives and their biological evaluation Open
A series of novel benzimidazole derivatives have been synthesized by the condensation of o -phenylenediamine with 4-bromophenoxy acetic acid and product obtained was alkylated at the benzimidazole -NH with different electrophilic reagents.…

An Efficient One-Pot Synthesis of Polyhydroquinolines at Room Temperature Using HY-Zeolite Open
An efficient one-pot synthesis of polyhydroquinolines by four-component coupling reactions of aldehydes, ethyl acetoacetate, dimedone and ammonium acetate in the presence of HY-zeolite at ambient temperature has been achieved. The conversi…
