BACKGROUND Leishmaniasis is a neglected tropical parasitic diseases affecting millions of people around the globe. Quinazolines are a group of compounds with diverse pharmacological activities. Owing to their promising antileishmanial activities, some 3-aryl-2-(substitutedstyryl)-4(3H)-quinazolinones were synthesized in good yields (65.2% to 86.4%). RESULTS The target compounds were synthesiz...

quinazolinones are interesting materials because of their valuable biological effects. in this study some new 2,3-disubstituted-4(3h)quinqzolinone derivatives were synthesized from anthranilic acid in six steps by introducing a new chiral center to the aliphatic side chain of the quinazolinone. in the last step, a single acylation on the hydrazine moiety afforded final compounds. the structures...

The present work describes convenient synthesis of the novel Schiff bases 4, 5 and 6 by reaction each previously synthesized quinazolinones 1, 2 3 with p-methoxybenzaldehyde. [2+2] Cycloaddition Reaction former within phenylisothiocyanate affording azatedine derivatives 7 8. Also, quinazolines 1 could be reacted α-bromoglucose tetraacetate giving peracetylated N-glycosides 9 10 which were then ...

A convenient protocol for the one-pot synthesis of quinazolin-4(3H)-ones using palladium(II) complexes via dehydrogenative coupling readily available benzyl alcohols and 2-aminobenzamide has been described. New structurally related Pd(II) N^O chelating general configuration [Pd(L)Cl(PPh3)] (where L = dimethylamino benzoylhydrazone ligands) have designed synthesized. The formation recognized by ...
