Call for Papers
The 15th International Electronic Conference on Synthetic Organic Chemistry (ECSOC-15) will run from 1 - 30 November 2011. ECSOC-15 Proceedings will be published later online and as a CD-ROM edition (ISBN: 3-906980-25-1). Posters presented at ECSOC-15 may be considered as preliminary communications of new research results or review papers and may be published in another form later in any standard journal. At the authors discretion, contributions will be removed from the web-site after the end of the conference and not included in the online and CD-ROM proceedings editions. Authors are invited to publish their papers subsequently in Molecules.
The 15th International Electronic Conference on Synthetic Organic Chemistry (ECSOC-15) will cover timely research topics concerned with synthetic organi chemistry. The conference will be divided into 5 topical sessions. The first session wil be related to general organic synthesis (Section A). The second session will focus on bioorganic, medicinal and natural products (Section B). The third session will be a symposium on microwave assisted aynthesis (Section C). The fourth session will be related to polymer and supramolecular chemistry (Section D). Finally, the last session will focus on computational chemistry (Section E).

Instructions for Authors
Authors are encouraged to preare a couple of slides in PowerPoint or similar software, to be displayed online along with the Communication. Slides, if available, will be displayed directly in the website using Sciforum.net's proprietary slides viewer. Slides can be prepared in exactly the same way as for any traditional conference where research results can be presented. Slides should be converted to the PDF format before submission so that our process can easily and automatically convert them for online displaying.
Submissions should be done by the authors online by registering with www.sciforum.net, and using the "New Submission" function once logged into system.
MDPI AG, the publisher of the Sciforum.net platform, is an open access publisher. We believe that authors should retain the copyright to their scholarly works. Hence, by submitting a Communication paper to this conference, you retain the copyright of your paper, but you grant MDPI AG the non-exclusive right to publish this paper online on the Sciforum.net platform. This means you can easily submit your paper to any scientific journal at a later stage and transfer the copyright to its publisher (if required by that publisher).

N\'-[(4-oxochromen-3-yl)methylidene]-4-R-furo[3,2-b]pyrrole-5-carboxhydrazides 3 were prepared by treatment of substituted carboxhydrazides 1 with 4-oxo-4H-chromen-3-carboxaldehyde 2 in ethanol in the presence of p-TsOH. Compounds 3 were subsequently used as ligands in complexation reactions with solutions of metal (M2+) chlorides or nitrates: [Ni(NO3)2.6H2O, Co(NO3)2.6H2O, CoCl2.6H2O, CuCl2.2H2O] to give complexes 4. | |||||||||||||||||||||||||||||||||||||||||

Indenoisoquinolinediones, as exemplified by lead compounds indotecan and indimitecan, are a class of non-camptothecin topoisomerase I poisons that display marked cytotoxic properties and for some of them antitumor activities in xenograft models. We have developed two alternative and dramatically different synthetic approaches to a variety of highly fused and diversely substituted models that differ from the elaboration of key precursors, i.e. arylated 2,3-dihydroisoquinolones. The first one is based upon a Suzuki-Miyaura cross-coupling reaction involving enol phosphates combined with a ring-closing metathesis (RCM) reaction to ensure the creation of the six-membered lactam unit. The second approach hinges upon the photoinduced electrocyclization of the 6π electron aromatic enamides. The presence of phenolic methoxy groups precluded an additional mandatory and problematic oxidation step to generate the unsaturated lactam ring. Intramolecular carbocationic annulation reaction and ultimate oxidation of the latent hydroxyl functionality completed the synthesis of the targeted title compounds. | |||||||||||||||||||||||||||||||||||||||||

α-Alkylidene-γ-lactams and lactones are the active constituents of many natural and synthetic compounds exhibiting pronounced biological properties. They are able to act as Michael acceptors in the reaction with thiol groups of bionucleophiles or can readily form [2 + 2] cycloadducts with DNA bases. We have developed concise synthetic approaches towards exemplary representatives of α-methylene models that hinges upon the preliminary assembly of the lactam and lactone template. Subsequent installation of the methylidene by a metallation/alkylation/elimination sequence completed the elaboration of the racemic title compounds. The presence of a quaternary carbon center bearing the carboxylate function precluded the undesirable isomerization leading to the corresponding endocyclic unsaturated analogues. | |||||||||||||||||||||||||||||||||||||||||

The object of the present study is the isodesmic reaction of cellobiose (the repeating unit in cellulose) with different kinds of silanes, R-SiH3, to form silylated cellobiose (Cello-SiH3) and the corresponding alcohols (R-OH). The size and the chemical reactivity of the substituent R is varied as well as the position where O-silylation at the cellobiose takes place. In contrast to experimental observations where the O6 position is favored for silylation, for the computed reactions, energy differences are smaller than 3 kcal/mol for the different positions at the B3LYP/6-311G* as well as at the B3LYP/6-311+G* level of theory. Depending on the silane, reaction energies in a range from -17 kcal/mol (R=NHSiH3) and +18 kcal/mol (R=F) have been calculated. In addition, semi-empirical calculations on the PM3 level of theory have been performed. These results are set into contrast with the results derived from DFT calculations to assess whether semi-empirical methods may be useful for the description of larger systems containing silylated cellobiose units. Acknowledgements: The research leading to these results has received funding from the European Community\'s Seventh Framework Programme [FP7/2007–2013] under grant agreement no. 214015 (S.S. and H.M.A.E.) and no. 214653. | |||||||||||||||||||||||||||||||||||||||||
sciforum-001979 | Synthesis and properties of cyclodextrin-malic acid copolymers | , | N/A |
Show Abstract |
|||||||||||||||||||||||||||||||||||||
Cyclodextrins polymers are known as an interesting low molecular carriers in pharmacy, food technology, medicine etc. There are different routes to design such kind of macromolecules however most of them base on synthetic compound. In the presented work a series of cyclodextrin polyesters with malic acid were obtained using dry method. Sodium hydrogen phosphate was used as a catalyst. As a result two different fractions were obtained i.e. water soluble and insoluble ones. Both of them were characterized by means of carboxylic acid (HPLC) and carbohydrates profile (anthron method) . Several malic acid derivatives were detected especially fumaric and malonic acids. In obtained sample the complexation ability was checked using standard methyl orange method. The insoluble fraction was hydrolyzed using sodium carbonate solution and the carboxylic acids and cyclodextrin presence were investigated as well. According to obtained results we can state the novel cyclodextrin macromolecules were design using simple and easy protocol. The obtained product is fully biodegradable and completely nontoxic what guides to many possible application in both food and non-food application. |
