We report the synthesis of alpha-aminonitriles by one-pot coupling reaction of aldehyde, amines and trimethylsilyl cyanide (TMSCN) using beta-ketoiminato zinc complexes as a pre-catalyst in very good yield under mild reaction condition. Homoleptic zinc complex [{kappa(2)-(2,4,6-Me3C6H2NC(Me)=CHC(Me)=O)}(2)Zn] (1 a) was synthesized by the treatment of protic ligand [(2,4,6-Me3C6H2NHC(Me)=CHC(Me)=O)] ((LH)-H-1) with potassium hydride and anhydrous zinc diiodide in 2 : 2 : 1 molar ratio in THF. Analogous reactions using [(2,6-(Pr2C6H3NHC)-Pr-i(Me)=CHC(Me)=O)] ((LH)-H-2) and [(Ph2CHNHC(Me)=CHC(Me)=O)] ((LH)-H-3) as protic ligands, dinuclear zinc complexes [{kappa(3)-(2,6-(Pr2C6H3NC)-Pr-i(Me)=CHC(Me)=O)}ZnI](2)(1 b) and [Zn(Ph2CHNHC-(Me)=CHC(Me)=O)ZnI2] (1 c) were obtained in good yield. Molecular structures of ligandsL(1)H,(LH)-H-3, and zinc complexes1 a,1 b, and1 cwere established by single-crystal x-ray diffraction analysis. Dinuclear zinc complexes1 b, and1 cexhibited high transformation, greater selectivity and broad substrate scope for the synthesis of alpha-aminonitrile under mild condition. A most plausible mechanism for synthesis alpha-aminonitrile is proposed based on several controlled reactions.

Herein we report the iron-catalyzed beta-C(sp(3))-methylation of primary alcohols using methanol as a Cl building block. This borrowing hydrogen approach employs a well-defined bench-stable (cyclopentadienone)iron(0) carbonyl complex as precatalyst (5 mol %) and enables a diverse selection of substituted 2-arylethanols to undergo beta-C(sp(3))-methylation in good isolated yields (24 examples, 65% average yield).

The chorismate mutase (CM) is considered as an attractive target for the identification of potential antitubercular agents due to its absence in animals but not in bacteria. A series of 3-indolylmethyl substituted pyrazolo-triazinone derivatives were designed and docked into CM in silico as potential inhibitors. These compounds were efficiently synthesized using the Pd/Cu-catalyzed coupling-cyclization in a single pot involving the construction of indole ring. The methodology was later extended to the preparation of corresponding benzo analogs of pyrazolotriazinones i.e. 3-indolylmethyl substituted benzotriazinone derivatives. Several of these novel compounds showed significant inhibition of CM when tested in vitro at 30 mu M. The SAR (Structure-Activity-Relationship) studies suggested that benzotriazinone moiety was more favorable over the pyrazolotriazinone ring. The two best active compounds showed IC50 similar to 0.4-0.9 mu M (better than the reference/known compounds used) and no toxicity till 30 mu M in vitro.

Click chemistry is a concept in which modular synthesis is used to rapidly find new molecules with desirable properties(1). Copper(I)-catalysed azide-alkyne cycloaddition (CuAAC) triazole annulation and sulfur(VI) fluoride exchange (SuFEx) catalysis are widely regarded as click reactions(2-4), providing rapid access to their products in yields approaching 100% while being largely orthogonal to other reactions. However, in the case of CuAAC reactions, the availability of azide reagents is limited owing to their potential toxicity and the risk of explosion involved in their preparation. Here we report another reaction to add to the click reaction family: the formation of azides from primary amines, one of the most abundant functional groups(5). The reaction uses just one equivalent of a simple diazotizing species, fluorosulfuryl azide(6-11) (FSO2N3), and enables the preparation of over 1,200 azides on 96-well plates in a safe and practical manner. This reliable transformation is a powerful tool for the CuAAC triazole annulation, the most widely used click reaction at present. This method greatly expands the number of accessible azides and 1,2,3-triazoles and, given the ubiquity of the CuAAC reaction, it should find application in organic synthesis, medicinal chemistry, chemical biology and materials science.

The good leaving tendency of the benzotriazole moiety has been exploited for the synthesis of symmetric, unsymmetric, N-acyl, and cyclic ureas in good yields from N-acylbenzotriazoles by treating the latter with various amines in the presence of TMSN N in a sealed tube. The salient features of the devised protocol includes the high-yield, mild, metal-free, one-pot reaction conditions, and short reaction time. Furthermore, in many cases, no column chromatography is required for the purification.

An efficient Ru-catalyzed asymmetric hydrogenation of dibenzo[c,e]azepines is reported. A series of seven-membered cyclic amines were obtained with moderate to excellent enantioselectivity. The catalyst counteranion played an important role in achieving high-level chiral induction. Moreover, a one-pot synthesis of chiral 6,7-dihydro-5H-dibenz[c,e]azepines via two-step reductive amination was also developed.

We present a novel series of radioiodinated tracers and potential theranostics for diseases accompanied by pathological function of proteins involved in choline transport. Unlike choline analogues labeled with C-11 or F-18 that are currently used in the clinic, the iodinated compounds described herein are applicable in positron emission tomography, single-photon emission computed tomography, and potentially in therapy, depending on the iodine isotope selection. Moreover, favorable half-lives of iodine isotopes result in much less challenging synthesis by isotope exchange reaction. Six of the described compounds were nanomolar ligands, and the best compound possessed an affinity 100-fold greater than that of choline. Biodistribution data of I-125-labeled ligands in human prostate carcinoma bearing (PC-3) mice revealed two compounds with a biodistribution profile superior to that of [F-18]fluorocholine.

Construction of N-substituted pyrrolidones from biomass-derived levulinic acid (LA) via reductive amination is a highly attractive route for biomass valorization. However, realizing this transformation using H-2 as the hydrogen source under mild conditions is still very challenging. Herein, we designed porous TiO2 nanosheets-supported Pt nanoparticles (Pt/P-TiO2) as the heterogeneous catalyst. The prepared Pt/P-TiO2 was highly efficient for reductive amination of LA to produce various N-substituted pyrrolidones (34 examples) at ambient temperature and H-2 pressure. Meanwhile, Pt/P-TiO2 showed good applicability for reductive amination of levulinic esters, 4-acetylbutyric acid, 2-acetylbenzoic acid, and 2-carboxybenzaldehyde. Systematic studies indicated that the strong acidity of P-TiO2 and the lower electron density of the Pt sites as well as the porous structure resulted in the excellent activity of Pt/P-TiO2.

Metal-free, visible-light-induced denitrogenative phosphorylation of 1,2,3-benzotriazinones was achieved. With the use of eosin Y as a photoredox catalyst, N,N-diisopropylethylamine as a base, CH3CN-H2O as a solvent and sunlight or a blue LED as a light source, a variety of aryl-phosphonates, aryl-phosphinates, and aryl-phosphine oxides were efficiently prepared. In addition, B(2)pin(2) instead of P-nucleophiles as a radical acceptor was also demonstrated. The key advantages of this newly developed method are the clean reaction profile, use of a low-cost organic-dye catalyst, energy efficiency, broad substrate scope, good to excellent yields and large-scale synthetic applicability. The gram-scale synthesised compounds could be isolated in pure form just upon extraction, followed by re-crystallisation; no tedious chromatographic purification was required.
