ASYMMETRIC DIELS-ALDER REACTION OF OPTICALLY-ACTIVE ALPHA-(2-EXO-HYDROXY-10-BORNYL)SULFINYLMALEIMIDES AND ITS APPLICATION TO OPTICALLY-ACTIVE 5-FUNCTIONALIZED PYRROLINES VIA RETRO-DIELS-ALDER REACTION

Optically pure sulfinylmaleimides 1 have been synthesized. The Diels-Alder reactions of the sulfoxides 1 with various dienes showed high diasteroselectivity. Regioselective reduction of the adducts 4c and 6c followed by desulfinylation afforded the gamma-hydroxy lactams 17 and 27, respectively. N-Acyliminium additions using compounds 17 and 27 proceeded diastereoselectively to give gamma-alkyl lactams 23 and 29 by virtue of its conformationally rigid, bicyclo[2.2.1]- and 7-oxabicyclo[2.2.1]-heptene moiety. respectively. The use of compound 29 allows a simple preparation of chirally 5-functionalised Delta(3)-pyrrolin-2-ones of high optical purity such as compound 25 via retro-Diels-Alder reaction, whereas the thermal cycloreversion of adduct 23 required such forcing conditions as flash vacuum pyrolysis.

Design and synthesis of a competent pyrrolinone-peptide hybrid ligand for the class II major histocompatibility complex protein HLA-DR1

The design and synthesis of two pyrrolinone-peptide hybrid ligands (3 and 20) for the rheumatoid arthritis-associated class II MHC HLA-DR1 protein are described. The hybrids incorporate bispyrrolinones 4 and 21 as tetrapeptide mimics for amino acids VKQN (residues 309-312) of the virus hemagglutinin peptide HA 306-318 (PKYVKQNTLKLAT). Ligand construction employed our polypyrrolinone synthetic protocol, in conjunction with Fmoc-based solid-phase peptide synthesis. Bioaffinity studies reveal that hybrid ligand 3 bound the HLA-DR1 protein with affinity (IC50 = 137 nM) comparable to those of both the native HA 306-318 peptide (IC50 = 89 nM) and a control peptide (IC50 = 176 nM). This result demonstrates that the polypyrrolinone scaffold can be employed in the construction of bioactive peptide hybrid ligands, thus considerably expanding the scope and utility of the pyrrolinone scaffold.

Late-Stage Transformation of Carboxylic Acids to N-Trifluoroethylimides with Trifluoromethyl Diazomethane

We report the first systematic evaluation of the reaction of trifluoromethyl diazomethane (2,2,2-trifluorodiazoethane, CF3CHN2) with drug-like molecules. We found our previous copper-catalyzed transformation of carboxylic acids to the corresponding N-trifluoroethylimides with CF3CHN2 and acetonitrile is well-suited for the latestage modification of drug and drug-like acids. A procedure that enables the use of solid nitriles and nitriles with high boiling points as viable substrates is also disclosed.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.I hope my blog about 29331-92-8 is helpful to your research. Synthetic Route of 29331-92-8.

Nitrile group as IR probe to detect the structure and hydrogen-bond properties of piperidinium/pyrrolidinium based ionic liquids and acetonitrile mixtures

The use of molecular solvents has been proposed as a simple solution to reduce the high viscosities of neat ionic liquids (ILs) and extend the practical applications of ILs. A proper understanding of the structure and intermolecular interaction is of vital importance for the design, optimization and synthesis of ILs systems with tailored properties for specific applications. In this work, the structure and hydrogen-bond features of the representative pyrrolidinium/piperidinium based ILs and acetonitrile mixtures were studied by a combination of Fouriertransform infrared spectroscopy (FTIR) and density functional theory (DFT) calculations. The nu(C N) region is sensitive to the microenvironment and is used as IR probe to detect the structure and hydrogen-bond properties of the two IL-acetonitrile binary systems in the whole concentration range. Positive peaks are observed in the excess IR spectra of nu(C N) region which indicates the non-ideality of the mixing process and the formation of hydrogen-bonded complexes in the mixtures. With the help of deconvolution and DFT calculations, the species transformation in the mixing process can be identified from the excess spectra: When x(CD3CN) is less than 0.90, acetonitrile mainly interacts with the ion pairs and ion clusters of the ILs. Ion clusters are all broken out into ion pairs and the interaction complex is mainly ion pair-CD3CN when x(CD3CN) > 0.90. In the whole concentration range, the CD3CN cannot break apart the strong coulombic interactions between the cation and anion, and the individual cation and anion do not exist in the mixtures. All of the hydrogen-bonds in the ion pair/ion clusteracetonitrile complexes are weak strength, closed shells and electrostatically dominant interactions. (C) 2020 Published by Elsevier B.V.

The vibrational group frequency of the N-O-center dot stretching band of nitroxide stable free radicals

The group frequency of the N-O radical stretching vibration has received scant attention in the literature. The few existing treatments of the vibrational spectroscopy of nitroxides are incomplete at best and potentially misleading to workers in the field. To close this gap in the available knowledge, the existing literature on the vibrational spectra of nitroxide stable free radicals is critically reviewed with particular reference to the wavenumber position of the N-O-center dot stretching vibration, nu(N-O-center dot). Poor evidentiary bases for the assignment nu(N-O-center dot) were found in many instances. Ab initio Density Field Theory calculations using a model chemistry of UB3LYP at the 6-311 ++G(d,p) level were performed to obtain a theoretical band position of nu(N-O-center dot) for comparison with the published data. Large discrepancies between the theoretical and experimental values were found for the radical 3-carbamoyl-2,2,5,5-tetramethyl-3-pyrrolin-1-yloxyl, which currently sets the lower limit of the accepted wavenumber range of nu(N-O-center dot), as well as for the nitronyl and iminyl nitroxides. The wavenumber position of nu(N-O-center dot) was found to occur in the range 1450-1420cm(-1) for 5-membered cyclic nitroxides and 1395-1340 cm(-1) for 6-membered cyclic and acyclic nitroxides. In nitronyl nitroxides, the symmetric stretching vibration occurs in the region 1470cm(-1), but coupling to other modes makes specific band assignments problematic for the nitronyl nitroxide group.

De Novo Protocol for the Construction of Benzo[a]fluorenes via Nitrile/Alkene Activation

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, respectively. 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. Additionally, we demonstrated an alternative expeditious route for the synthesis of disubstituted benzo[a]fluorenes in the presence of TfOH alone.

SOLEIL and ALMA views on prototypical organic nitriles: C2H5CN

The high resolution vibrational spectrum of ethyl cyanide (C2H5CN) has been investigated in the far-IR using synchrotron-based Fourier transform spectroscopy. The assignment was performed using the Automated Spectral Assignment Procedure (ASAP) allowing accurate rotational energy levels of the four lowest fundamental vibrations of the species, namely the v(13) = 1 @ 205.934099(8)cm(1), v(21) = 1 @ 212.141101(8)cm(1), v(20) = 1 @ 372.635293(15)cm(1), and v(12) = 1 @ 532.699617(16)cm(1) states, to be determined. The analysis not only confirms the applicability of the ASAP in the treatment of (dense) high-resolution infrared spectra but also reveals some of its limitations. Complementary to the infrared study, the pure rotational spectrum of C2H5CN was also studied in selected frequency ranges from 75 to 255 GHz. New observations of a prototypical high-mass star-forming region, G327.3-0.6, performed with the Atacama Large Millimeter Array show that vibrational satellites of C2H5CN can be very intense, of order several tens of Kelvin in units of brightness temperature.
