Indenopyrans – synthesis and photoluminescence properties

27-Apr-2016 | Andreea Petronela Diac, Ana-Maria Ţepeş, Albert Soran, Ion Grosu, Anamaria Terec, Jean Roncali and Elena Bogdan, Beilstein Journal of Organic Chemistry, 2016

Abstract New indeno[1,2-c]pyran-3-ones bearing different substituents at the pyran moiety were synthesized and their photophysical properties were investigated. In solution all compounds were found to be blue emitters and the trans isomers exhibited significantly higher fluorescence quantum ...


cis–trans-Amide isomerism of the 3,4-dehydroproline residue, the ‘unpuckered’ proline

29-Mar-2016 | Vladimir Kubyshkin and Nediljko Budisa, Beilstein Journal of Organic Chemistry, 2016

Abstract Proline (Pro) is an outstanding amino acid in various biochemical and physicochemical perspectives, especially when considering the cis–trans isomerism of the peptidyl-Pro amide bond. Elucidation of the roles of Pro in chemical or biological systems and engineering of its features can ...


Aggregation behavior of amphiphilic cyclodextrins in a nonpolar solvent: evidence of large-scale structures by atomistic molecular dynamics simulations and solution studies

14-Jan-2016 | Giuseppina Raffaini, Fabio Ganazzoli and Antonino Mazzaglia, Beilstein Journal of Organic Chemistry, 2016

Abstract Chemically modified cyclodextrins carrying both hydrophobic and hydrophilic substituents may form supramolecular aggregates or nanostructures of great interest. These systems have been usually investigated and characterized in water for their potential use as nanocarriers for drug ...


Supramolecular polymer assembly in aqueous solution arising from cyclodextrin host–guest complexation

12-Jan-2016 | Jie Wang, Zhiqiang Qiu, Yiming Wang, Li Li, Xuhong Guo, Duc-Truc Pham, Stephen F. Lincoln and Robert K. Prud’homme, Beilstein Journal of Organic Chemistry, 2016

Abstract The employment of cyclodextrin host–guest complexation to construct supramolecular assemblies with an emphasis on polymer networks is reviewed. The main driving force for this supramolecular assembly is host–guest complexation between cyclodextrin hosts and guest groups either of which ...


Physical properties and biological activities of hesperetin and naringenin in complex with methylated β-cyclodextrin

29-Dec-2015 | Waratchada Sangpheak, Jintawee Kicuntod, Roswitha Schuster, Thanyada Rungrotmongkol, Peter Wolschann, Nawee Kungwan, ..., Beilstein Journal of Organic Chemistry, 2015

Abstract The aim of this work is to improve physical properties and biological activities of the two flavanones hesperetin and naringenin by complexation with β-cyclodextrin (β-CD) and its methylated derivatives (2,6-di-O-methyl-β-cyclodextrin, DM-β-CD and randomly methylated-β-CD, RAMEB). The ...


Friedel–Crafts-type reaction of pyrene with diethyl 1-(isothiocyanato)alkylphosphonates. Efficient synthesis of highly fluorescent diethyl 1-(pyrene-1-carboxamido)alkylphosphonates and 1-(pyrene-1-carboxamido)methylphosphonic acid

04-Dec-2015 | Anna Wrona-Piotrowicz, Janusz Zakrzewski, Anna Gajda, Tadeusz Gajda, Anna Makal, Arnaud Brosseau and Rémi Métivier, Beilstein Journal of Organic Chemistry, 2015

Abstract Friedel–Crafts-type reaction of pyrene with diethyl 1-(isothiocyanato)alkylphosphonates promoted by trifluoromethanosulfonic acid afforded diethyl 1-(pyrene-1-carbothioamido)alkylphosphonates in 83–94% yield. These compounds were transformed, in 87–94% yield, into the corresponding ...


Continuous formation of N-chloro-N,N-dialkylamine solutions in well-mixed meso-scale flow reactors

02-Dec-2015 | A. John Blacker and Katherine E. Jolley, Beilstein Journal of Organic Chemistry, 2015

Abstract The continuous flow synthesis of a range of organic solutions of N,N-dialkyl-N-chloramines is described using either a bespoke meso-scale tubular reactor with static mixers or a continuous stirred tank reactor. Both reactors promote the efficient mixing of a biphasic solution of ...


Synthesis, structure, and mechanical properties of silica nanocomposite polyrotaxane gels

16-Nov-2015 | Kazuaki Kato, Daisuke Matsui, Koichi Mayumi and Kohzo Ito, Beilstein Journal of Organic Chemistry, 2015

Abstract A significantly soft and tough nanocomposite gel was realized by a novel network formed using cyclodextrin-based polyrotaxanes. Covalent bond formation between the cyclic components of polyrotaxanes and the surface of silica nanoparticles (15 nm diameter) resulted in an infinite ...


2-Hetaryl-1,3-tropolones based on five-membered nitrogen heterocycles: synthesis, structure and properties

12-Nov-2015 | Yury A. Sayapin, Inna O. Tupaeva, Alexandra A. Kolodina, Eugeny A. Gusakov, Vitaly N. Komissarov, Igor V. Dorogan, N ..., Beilstein Journal of Organic Chemistry, 2015

Abstract A series of derivatives of 2-hetaryl-1,3-tropolone (β-tropolone) was prepared by the acid-catalyzed reaction of 2-methylbenzoxazoles, 2-methylbenzothiazoles and 2,3,3-trimethylindoline with 3,4,5,6-tetrachloro-1,2-benzoquinone. The molecular structures of the three representative ...


Photoinduced 1,2,3,4-tetrahydropyridine ring conversions

11-Nov-2015 | Baiba Turovska, Henning Lund, Viesturs Lūsis, Anna Lielpētere, Edvards Liepiņš, Sergejs Beljakovs, Inguna Goba and J ..., Beilstein Journal of Organic Chemistry, 2015

Abstract Stable heterocyclic hydroperoxide can be easily prepared as a product of fast oxidation of a 1,2,3,4-tetrahydropyridine by 3O2 if the solution is exposed to sunlight. The driving force for the photoinduced electron transfer is calculated from electrochemical and spectroscopic data. The ...
