nitroarenes to anilines catalyzed by well‐defined diimino and diamino cubane‐type Mo3S4 clusters. The novel diimino [Mo3S4Cl3(dnbpy)3]+ ([5]+) (dnbpy=4,4′‐dinonyl‐2,2′‐dipyridyl, L1) trinuclear complex was synthesized in high yields by simple ligand substitution reactions starting from the thiourea (tu) [Mo3S4(tu)8(H2O)]Cl4⋅4 H2O (3) precursor. This strategy has also been successfully adapted for the isolation
We report the discovery and preliminary SAR studies of a series of structurally novel benzotriazine core based small molecules as inhibitors of Src kinase. To the best of our knowledge, benzotriazine template based compounds have not been reported as kinase inhibitors. The 3-(2-(1-pyrrolidinyl)ethoxy)phenyI analogue (43) was identified as one of the most potent inhibitors of Src kinase. (c) 2006 Elsevier Ltd. All rights reserved.
Synthesis of Quinoxaline 1,4-Dioxides from Benzofuroxan Proceeds Not in, But on Zeolite
Quinoxaline synthesis using Na-zeolite A as a catalyst to proceeds in a better yield than that using zeolite X. The pore diameter of zeolite X is large enough to allow the benzofuroxan derivatives access to cages, therefore part of benzofuroxan is adsorbed in the internal surface of zeolite X. Whereas the windows to the cages of Na-zeolite A are too small to allow the benzofuroxan derivatives access to the cages, therefore all the benzofuroxan is adsorbed on the external surface of zeolite. The reactions of benzofuroxans with benzoylacetone was catalyzed by zeolite proceed not in, but on zeolite.
