A range of 2-substituted-4,6-dimethoxy activated benzimidazoles and 2,2'-bisbenzimidazoles have been synthesized from 2-aminoanilide derivatives under acidic conditions. The starting materials were prepared either by acylation from 3,5-dimethoxyaniline followed by nitration, or by acylation from 3,5-dimethoxy-2-nitroaniline. The 2-nitroanilides were then reduced by palladium catalyzed reaction with hydrazine and subsequent acid catalyzed cyclization giving the corresponding 4,6-dimethoxybenzimidazoles and 4,6-dimethoxy-2,2'-bisbenzimidazoles. In addition, 2-phenyl-4,5,6-trimethoxybenzimidazole has been synthesized using a similar procedure.

Acute lymphoblastic leukemia (ALL) is the most common type of leukemia in children. Up to a quarter of ALL patients relapse and face poor prognosis. To identify new compound leads, we conducted a phenotypic screen using terrestrial natural product (NP) fr
Synthesis of heterocycle-based analogs of resveratrol and their antitumor and vasorelaxing properties

New resveratrol (RES) analogs were developed by replacing the aromatic 'core' of our initial naphthalene-based RES analogs with pseudo-heterocyclic (salicylaldoxime) or heterocyclic (benzofuran, quinoline, and benzothiazole) scaffolds. The resulting analo
Alkoxy- and amidocarbonylation of functionalised aryl and heteroaryl halides catalysed by a Bedford palladacycle and dppf: A comparison with the primary Pd(II) precursors (PhCN)2PdCl2 and Pd(OAc) 2

The versatility of a Bedford-type palladacycle 1, namely [{Pd(-Cl){κ2-P,C-P(OC6H2-2,4- tBu2)(OC6H3-2,4-tBu 2)2}}2], as a primary Pd source, in combination with the ligand bis-1,1′-(diphenylphosphino)ferrocene (dppf) has been established in carbonylation reactions of aryl and heteroaryl bromides with methanol, piperidine and related nucleophiles. Palladacycle 1 has been compared with other primary Pd sources, e.g. (PhCN)2PdCl2 and Pd(OAc)2. The efficacy of the carbonylation processes appear to be linked to the [Pd] concentration, substrate: catalyst ratio, CO pressure and reaction temperature. In amidocarbonylation, double carbonylation is observed for certain organohalides. In the case of 2,5-dibromopyridine, regioselective amination (Hartwig-Buchwald type) also occurs as a side-reaction.

The synthesis of 2-aryl-3,5,7-trimethoxy-4-quinolones was accomplished in three steps starting from 3,5-dimethoxyaniline and an aroyl chloride. These structures might be used as potential flavonol analogs. (C) 2000 Elsevier Science Ltd.
