A series of 2-oxopyrimido[4,5-b]-, 2-thio[4,5-b]-, 1-(p-tosyl)pyrazolo[3,4-b]- and 1-(2',4'-dinitrophenyl)pyrazolo[3,4-b]-quinolines have been synthesized in good to excellent yields by environmentally benign solvent free microwave-induced techniques involving the condensation of 2-chloro-3-formylquinolines with urea, thiourea, p-toluenesulfonylhydrazide(More)
Some new substituted tetrahydroacridin-8-ones and diverse derivatives were synthesized by uncatalysed multi-component reaction of dimedone or cyclohexan-1,3-dione, alpha-naphthylamine and various (o,p,m)-substituted benzaldehydes. The in vitro anti-microbial activities of the prepared compounds were evaluated against some bacteria and fungi strains. The(More)
The microwave-induced three-component one-pot synthesis of 2-amino-3-carbethoxy-4-phenylpyrano[3,2-c]quinolin-5(6H)-ones (4a–l) from 4-hydroxyquinolin-2(1H)-ones, aromatic aldehydes and ethyl cyanoacetate was described. The detailed synthesis, structure analysis, and antimicrobial screening for the title compounds were also reported. Pharmacological screen(More)
A series of pyrimido[4,5-b]quinolin-2,4(1H,3H)-dione derivatives (5-deazaalloxazines) was synthesized by the reaction of various substituted 2-chloroquinolin-3-carboxylic acids with urea/thiourea. The structure of these newly synthesized compounds was characterized by standard spectroscopic and analytical techniques. The antimicrobial activities of the(More)
