[source] Towards the Synthesis of Highly Functionalized Chiral ,-Amino Nitriles by Aminative Cyanation and Their Synthetic ApplicationsEUROPEAN JOURNAL OF ORGANIC CHEMISTRY, Issue 1 2006Luca Bernardi Abstract The cyanobis(dibenzylamino)borane-mediated transformation of chiral aldehydes into the corresponding ,-amino nitriles is described. Starting from these compounds short synthetic routes can be envisaged for obtaining diastereomerically pure functionalized 1,2-diamines and hydroxylated ,-amino acids that are of interest as core key units of biologically active substances or as potential ligands for asymmetric catalysis. The stereochemical outcome of the aminative cyanation reaction is discussed. (© Wiley-VCH Verlag GmbH & Co.

Ismail Abstract 6-[5-(4-Amidinophenyl)furan-2-yl]nicotinamidine- d4 (5) was synthesized from 6-[5-(4-cyanophenyl)furan-2-yl]nicotinonitrile- d4 (3), through the bis - O -acetoxy-amidoxime followed by hydrogenation. Compound 3 was prepared from 6-(furan-2-yl)-nicotinonitrile by a Heck coupling reaction with 4-bromobenzonitrile- d4, a product of selective cyanation reaction of 1,4-dibromobenzene- d4 with Cu(1)CN. Deuterium-labelled N -methoxy-6-{5-[4-(N -methoxy-amidinophenyl]-furan-2-yl}-nicotinamidines were prepared via methylation of their respective amidoximes with dimethyl sulfate- d6 in aqueous sodium hydroxide in good yields.

[source] Palladium-catalyzed cyanation reaction of aryl halides using K4[Fe(CN)6] as non-toxic source of cyanide under microwave irradiationAPPLIED ORGANOMETALLIC CHEMISTRY, Issue 6 2010Abdol R. Hajipour Abstract An efficient method for preparation of aryl nitriles,using [Pd{C6H2(CH2CH2 NH2)-(OMe)2,3,4} (µ-Br)]2 complex as an efficient catalyst and K4[Fe(CN)6] as a green cyanide source,from aryl bromides, aryl iodides and aryl chlorides under microwave irradiation has been reported. This complex has been demonstrated to be an active and efficient catalyst for this reaction. Using a catalytic amount of this synthesized palladium complex in DMF at 130 °C led to production of the cyanoarenes in excellent yields in short reaction times.
