A one pot synthesis of β-ketonitriles from readily accessible 3-chloropropenals using economically benign iodine, aqueous ammonia and sodium hydroxide solution, employing mild reaction conditions have been described. This report presents a convenient, inexpensive, highly toxic-matter-free and eco-friendly approach for β-ketonitriles.

Benzoylacetonitrile were prepared through sequential carbonylation and decarboxylation. The palladium-catalyzed carbonylation of aryl iodides and methyl cyanoacetate using Mo(CO)6 as a carbon monoxide source afforded beta-keto cyanoesters, and then the subsequent reaction with Li/H2O produced the desired benzoylacetonitriles.

In our drug discovery program, a series of 2-thioxo-pyrazolo[1,5-a][1,3,5] triazin-4-ones were designed, synthesized and evaluated for their TP inhibitory potential. All the synthesized analogues conferred a varying degree of TP inhibitory activity, comparable or better than positive control, 7-deazaxanthine (7-DX, 2) (IC50 value = 42.63 μM). A systematic approach to the lead optimization identified compounds 3c and 4a as the most promising TP inhibitors, exhibiting mixed mode of enzyme inhibition. Moreover, selected compounds demonstrated the ability to attenuate the expression of the angiogenic markers (viz. MMP-9 and VEGF) in MDA-MB-231 cells at sublethal concentrations. In addition, molecular docking studies revealed the plausible binding orientation of these inhibitors towards TP, which was in accordance with the experimental results. Taken as a whole, these compounds would constitute a new direction for the design of novel TP inhibitors with promising antiangiogenic properties.
Expanding the scaffold for bacterial RNA polymerase inhibitors: Design, synthesis and structure-activity relationships of ureido-heterocyclic-carboxylic acids

, p. 2177 - 2194 (2014/01/06)
The emergence of bacterial resistance requires the development of new antibiotics with an alternative mode of action. Based on class I, developed in our previous study, a new series of RNA polymerase (RNAP) inhibitors targeting the switch region was desig
Synthesis of benzoylacetonitriles from Pd-catalyzed carbonylation of aryl iodides and trimethylsilylacetonitrile
Park, Ahbyeol,Lee, Sunwoo
supporting information; experimental part, p. 1118 - 1121 (2012/03/27)
Palladium-catalyzed carbonylation of aryl iodides and trimethylsilylacetonitrile to produce benzoylacetonitrile derivatives through a one-pot, three-component reaction is described. This preparation method provides good yields of the carbonylated products without any additional ligands. It has a broad substrate scope with a high tolerance for a variety of functional groups.
Palladium-catalyzed carbonylation with Mo(CO)for the synthesis of benzoylacetonitriles
Pyo, Ayoung,Park, Ahbyeol,Jung, Hyunmin,Lee, Sunwoo
supporting information, p. 2885 - 2888 (2012/10/29)
Benzoylacetonitriles were synthesized by the palladium-catalyzed carbonylation of aryl iodides and trimethylsilylacetonitrile using Mo(CO)as a carbon monoxide source. Pd(PPhCland CuFwere employed as the catalyst and activator, respectively. A variety of aryl iodides bearing alkyl, alkoxy, fluoro, chloro, bromo, nitrile, ester, and ketone groups afforded the corresponding benzoylacetonitriles in moderate to good yields.
