Temperature Dependence of Hyperfine Interaction for N-15 Nitroxide in a Glassy Matrix at 10-210 K

Principal N-15 hyperfine interaction (hfi) values in N-15-substituted nitroxide spin probe 3-carbamoyl-2,2,5,5-tetramethyl-3-pyrrolin-1-oxyl dissolved in nematic liquid crystal 4-pentyl-4′-cyanobiphenyl (5CB) were measured in a wide temperature range of 10-210 K, for 5CB frozen to a glassy state. X-band continuous-wave electron paramagnetic resonance (CW EPR) and pulse X- and Q-band N-15 electron-nuclear double resonance (ENDOR) techniques were employed. To avoid microwave saturation at low temperatures in CW EPR studies, a holmium complex Ho(Dbm)(3)Bpy (where Dbm is dibenzoylmethane and Bpy is 2,2′-bipyridine) was added. X-and Q-band N-15-ENDOR data have shown that the nitroxide hfi tensor is axially symmetric. The combination of data from all techniques allowed us to obtain the temperature dependence of isotropic and anisotropic parts of the nitroxide hfi tensor. Above similar to 100 K, a linear dependence of the anisotropic hfi value was observed, whereas below 30 K it was found to be nearly temperature independent. Such a behavior can be interpreted using the model of restricted orientational motions (librations) of a spin probe in a glassy matrix, with quantum effects occurring at low temperature (freezing of the librations). The energy quantum for the libration motion estimated from the temperature dependence of hfi of the spin probe is 84 cm(-1). Low-frequency Raman spectra of 5CB were also obtained, which provided the mean vibrational frequency of 76 cm(-1) for glassy 5CB.

Reactions with pyrrolidine-2,4-diones, part 4*: Synthesis of some 3-substituted 1,5-diphenylpyrrolidine-2,4-diones as potential antimicrobial, anti-HIV-1 and antineoplastic agents

The condensation of 1,5-dipheiiylpyrrolidine-2,4-dione (1) with ethyl orthoformate yielded 3-ethoxymethylene-1,5-diphenylpyrrolidinc-2,4-dione (2). Reaction of the latter with hydrazine hydrate, secondary amines 7a-c or urea afforded the corresponding 3-substituted aminomethylene-1,5-diphenylpyrrolidene-2,4-diones 3, 8a-c or 9. On the other hand, condensation of 3 With veratraldehyde (5a) yielded 3-[(3,4-dimethoxybenzylidene)hydrazinomethylene]-1,5-diphenylpyrrolidine-24-dione (6). Whereas, cyclization of 9 with the reactive malonate ester 11 produced 3-[(5-butyl-4-hydroxy-2,6dioxo- 1,2,3,6- tetralhydropyrimidin-1-yl) methylene]-1,5-diphenylpyrrolidine-2,4-dione (12). The condensation of some selected aromatic aldehydes 5a-c and addition of morpholine (7c) or piperidine (7d) to some of the resulting 3-arylidene,1,5-diphenylpyrrolidine-2,4-diones 13b, e gave the respective 3-substituted methyl-4-hydroxy-1,5-diphenyl-Delta (3)-pyrrolin-2-ones 14a-c.

The first enantioselective dearomative [3+2] annulation of 5-amino-isoxazoles with quinone monoimines was realized using a chiral phosphoric acid as catalyst. Various novel (bridged) isoxazoline fused dihydrobenzofurans bearing two continuous quaternary stereocenters were achieved in moderate to good yields (up to 94%) with moderate to good enantioselectivities (up to 98% ee). The absolute configurations of two products were assigned by X-ray crystal structural analyses and a plausible reaction mechanism was proposed.

Magnetic cobalt ferrite nanoparticles functionalized with citric acid as a green nanocatalyst for one-pot three-component sonochemical synthesis of substituted 3-pyrrolin-2-ones

A clean, convenient and facile approach for one-pot ultrasonic assisted synthesis of substituted 3-pyrrolin-2-ones from diethyl acetylenedicarboxylate, aniline and aldehyde derivatives is described. The reactions were carried out in the presence of an efficient, green and reusable acidic nanocatalyst, magnetic cobalt ferrite nanoparticles functionalized with citric acid (CoFe2O4@CA), with high yields under mild conditions. Also, use of ultrasound irradiation made this approach an attractive protocol for the synthesis of these products. The method has been successful in achieving the green chemistry objective. An energy efficient protocol using ultrasound irradiation instead of conventional heating or stirring and use of ethanol as a non-hazardous, inexpensive and green solvent in the one-step reaction against sequential reaction steps thus combining the features of both economic and environmental advantages.

Different pathways in the reaction of N-(tosylmethyl)-substituted ureas, thioureas, and N ‘-cyanoguanidines with sodium cyanide. Synthesis of alpha-ureido nitriles, alpha-ureido amides, and hydantoin imino derivatives

Reaction of N-(tosylmethyl)-substituted ureas, thioureas, and N’-cyanoguanidines, prepared by condensation of the corresponding amides with various aldehydes and p-toluenesulfinic acid, with NaCN has been studied. The outcome of the reaction is strongly dependent on the amide nature and reaction conditions. Generally, N-(tosylmethyl)ureas afford alpha-ureido nitriles, N-(tosylmethyl)-N’-cyanoguanidines transform into 4-amino-2-cyanimino-1,5-dihydro-2H-imidazoles, and N-(tosylmethyl)thioureas give complex mixtures of various imidazole derivatives. The prepared alpha-ureido nitriles are selectively converted into the corresponding alpha-ureido amides by treatment with conc. HCl at room temperature. Under basic conditions, alpha-ureido nitriles cyclize into 4-amino-1,5-dihydro-2H-imidazole-2-ones. Treatment of 4-amino-2-cyanimino-1,5-dihydro-2H-imidazoles with conc. HCl at room temperature lead to hydrolysis of both the amidine fragment and cyano group to give hydrochlorides of 2-(carbamoylimino)imidazolidin-4-ones which are easily decarbamoylated to form hydrochlorides of 2-iminoimidazolidin-4-ones. Structure of the prepared imidazoles and some mechanistic aspects of cyanide-anion amidoalkylation with N-(tosylmethyl)ureas are discussed based on DFT calculations.

Acceptorless dehydrogenation of amines to nitriles catalyzed by N-heterocyclic carbene-nitrogen-phosphine chelated bimetallic ruthenium (II) complex

We have developed a clean, atom-economical and environmentally friendly route for acceptorless dehydrogenation of amines to nitriles by combining a new dual N-heterocyclic carbene-nitrogen-phosphine ligand R(CNP)(2) (R = o-xylyl) with a ruthenium precursor [RuCl2(eta(6)-C6H6)](2). In this system, the electronic and steric factors of amines had a negligible influence on the reaction and a broad range of functional groups were well tolerated. All of the investigated amines could be converted to nitriles in good yield of up to 99% with excellent selectivity. The unprecedented catalytic performance of this system is attributed to the synergistic effect of two ruthenium centers chelated by R(CNP)(2) and a plausible reaction mechanism is proposed according to the active species found via in situ NMR and HRMS.

Acetylenes and nitriles as unconventional reactants for aza-Wittig reactions

The classic version of aza-Wittig reactions, namely, reactions between phosphazenes and compounds with polar double bonds, is widely employed in organic synthesis to produce C=N bonds. However, only a limited number of aza-Wittig reactions between phosphazenes and compounds with triple bonds is known, which has a lot to do with certain structural features of the reactants, wherein additional activation is required. This review provides a guide to those rare examples of aza-Wittig reactions with acetylenes and nitriles. A unique trait of these atom-economic processes is that they afford Wittig or new aza-Wittig reagents, respectively, which offers new opportunities for employing these reactions in organic syntheses, especially those of N-heterocyclic compounds.
