Cl2CHCN and NH3 form 2,4,6-tris(dichloromethyl)-1,3,5-triazine and a black-brown polymer (I). Its infrared spectrum coincides with that of the polymer formed from dichloroacetamidine and NH3 and is very similar to the spectrum of paracyanogen. Elementary analysis of I shows the presence of O, probably introduced by hydrolysis. Polymerization of diethoxyacetonitrile, which has a lesser inductive effect of its C-X dipole than the dichloro compound, does not lead to tris(diethoxymethyl)-1,3,5-triazine. These 2 cases permit a general prediction about the course of the polymerization mechanism of HCN. The reaction has the same selectivity towards the catalyst as the benzoin condensation; the real catalyst is the cyanide ion.

Gao, Xiang; Liu, Jiao; Liu, Zhaopeng; Zhang, Lei; Zuo, Xin; Chen, Leyuan; Bai, Xue; Bai, Qingyun; Wang, Xinlin; Zhou, Anning published the artcile< DBU coupled ionic liquid-catalyzed efficient synthesis of quinazolinones from CO2 and 2-aminobenzonitriles under mild conditions>, Recommanded Product: 2-Amino-4-methoxybenzonitrile, the main research area is quinazolinone preparation organic base ionic liquid catalyst; aminobenzonitrile carbon dioxide cyclization diazabicycloundecene ionic liquid catalyst.

An efficient catalytic system of organic base-coupled ionic liquids (ILs) that could catalyze the synthesis of quinazolinones I (R1 = H, OMe, Cl, Br, R2 = H; R1 = H, R2 = Cl) via cyclization of 2-aminobenzonitriles with CO2 under mild conditions (e.g., 60°C, 0.1 MPa) was reported. It was found that 1,8-diazabicyclo[5.4.0]undec-7-ene coupled with 1-butyl-3-methylimidazole acetate ionic liquids, (DBU/[Bmim][OAc]), displayed excellent performance in catalyzing the reactions of CO2 with 2-aminobenzonitriles to give compounds I in high yields at atm. pressure. Moreover, the ILs had high stability and reusability, and could be reused at least five times without considerable decrease in catalytic activity. This protocol could also be conducted on a gram scale, and may have promising and practical applications in the production of quinazolinones.

A sequential multi-component reaction of β-ketonitriles with N,N-disubstituted hydrazines is designed and developed through a photocatalyzed intermol. amination process to afford hydrazonamides I [R = Et, Ph, 2-furyl, etc.; R1 = Me, Et, n-Pr, etc.; R2 = Ph, 3-MeC6H4, 4-ClC6H4, etc.]. This work reported the first example of the use of N,N-disubstituted hydrazines as two different “”amine”” sources, characterized by isotope labeling experiments The C-CN/N-N bonds were cleaved and new C-N/C=N bonds were constructed in a one-pot reaction. This protocol could be carried out without the addition of any external metals, ligands, bases, oxidants and reductants, and possessed the advantages of operational simplicity, mild reaction conditions, and good functional group tolerance. Furthermore, this approach enabled late-stage modifications of structurally complex bioactive mols., natural products and drugs, thus showing potential applications in the field of organo-pharmaceutical chem.

Bollini, Mariela; Domaoal, Robert A.; Thakur, Vinay V.; Gallardo-Macias, Ricardo; Spasov, Krasimir A.; Anderson, Karen S.; Jorgensen, William L. published the artcile< Computationally-Guided Optimization of a Docking Hit to Yield Catechol Diethers as Potent Anti-HIV Agents>, Product Details of C7H3ClFN, the main research area is catechol ether anti HIV reverse transcriptase inhibitor computational optimization.

A 5-μM docking hit has been optimized to an extraordinarily potent (55 pM) non-nucleoside inhibitor of HIV reverse transcriptase. Use of free energy perturbation (FEP) calculations to predict relative free energies of binding aided the optimizations by identifying optimal substitution patterns for Ph rings and a linker. The most potent resultant catechol diethers feature terminal uracil and cyanovinylphenyl groups. A halogen bond with Pro95 likely contributes to the extreme potency of compound 42 (I). In addition, several examples are provided illustrating failures of attempted grafting of a substructure from a very active compound onto a seemingly related scaffold to improve its activity.

Balwe, Sandip Gangadhar; Kim, Jong Su; Kim, Yeong-Il; Jeong, Yeon Tae published the artcile< Diversity-oriented one-pot synthesis of furan based densely substituted biheteroaryls via isocyanide insertion>, Category: nitriles-buliding-blocks, the main research area is aroylacetonitrile arylglyoxal Knoevenagel condensation isocyanide insertion cascade heterocyclization; biheteroaryl furan diversity oriented synthesis; PTSA Knoevenagel condensation isocyanide insertion cascade heterocyclization catalyst.

A facile and efficient acid-catalyzed cascade reaction for the synthesis of novel biheteroaryl structural motifs containing densely functionalized furans has been developed. The reaction sequence involves a Knoevenagel condensation of arylglyoxals with aroyl or heteroaroylacetonitrile and subsequently an isocyanide insertion via formal [4+1] cycloaddition followed by rapid [1,3]-H shift to afford uniquely decorated novel biheterocycles, e.g., I. Furthermore, the scope of the methodol. was extended to diverse biheteroaryls by employing 3-(2-furyl)-3-oxopropanenitrile, 3-cyanoacetyl-1-methylindole, 3-oxo-3-(1H-pyrrol-2-yl)propanenitrile, 3-(1H-indol-3-yl)-3-oxopropanenitrile, 3-oxo-3-(2-thienyl)propionitrile and benzoylacetonitriles.

A simple and efficient method for the construction of spiro[indoline-pyran] and fused (epoxyetheno)indeno[1,2-b]furan compounds from 1-cyanoketones and 1,2-diketone was developed. The synthesis proceeded via the Knoevenagel and Michael adduct through intramol./Paal-Knorr cyclization under similar reaction condition. The less commonly used 1-cyanoketones and active carbonyl compounds served as the indole containing pyran and bicyclic furan source for the preparation of a new series of heterocyclic compounds This heterocyclic structure allows one and more than one tetra-substituted carbon center and sequential hexa- and penta-cyclic core under very mild conditions and showed excellent chemo and regioselectivity. In addition, the synthesis of spiro[indoline-pyran] and (epoxyetheno)indeno[1,2-b]furan was demonstrated in a gram scale.

Unprecedented chemo- and regioselective synthesis of benzo[a]fluorenes and naphthamide-substituted benzo[a]fluorenes were constructed from the reaction of (E)-2-aroyl-3-(2-(arylalkynes/alkenes)aryl)acrylonitrile scaffolds under metal-free conditions via the activation of nitriles and alkenes, resp. A tentative reaction mechanism was proposed for this homofunctionalization of nitriles. Control experiments showed that the reaction proceeds via selective nitrile or alkene protonation, depending upon the substrates. Addnl., we demonstrated an alternative expeditious route for the synthesis of disubstituted benzo[a]fluorenes in the presence of TfOH alone.
