Syntheses and Structure of 8-, 7-, and 6-Membered Silacycloallenes
Decreasing the ring size of a cyclic allene to rings of fewer than 10 carbons results in deviation of both the normal C=C=C linearity and the orthogonality of the dihedral angle.' To date, the smallest isolable cycloallene is 1-tert-butyl-1,2-cyclooctadiene,2 and the smallest for which structural information is available is the phenylurethane derivative of cyclonona-2,3-dien-1-oJ,l which is ben...
متن کامل7. Conclusion 6. Some Extensions of Nafur
31 watch or listen to an activity with a high variation of QoS rather he/she prefers a steady QoS even it is not the best. Let us note that the proposed algorithms can be slightly modified to produce variable quality proposals. To present the details of such modifications is out of scope of the paper. This paper describes work on a new QoS negotiation approach with future reservations (NAFUR) t...

متن کاملSyntheses of some fluorescent ribonucleotides.
Synthesis of guanosine 3'-phosphodiesters of 1, N6-ethenoadenosine-2-sulfonate or 1, N6-etheno-2-azaadenosine can be done readily with ribonuclease N1. There is a 10-fold difference in quantum yield between the phosphodiesters and the starting fluorescent nucleosides. This difference provides the basis for the development of a fluorescent assay for nuclease.
متن کاملSyntheses and activities of some bactobolin derivatives.
Some derivatives of bactobolin were prepared from bactobolin by dehydration or substitution reactions through tris(dimethylamino)alkoxyphosphonium salt formation. A derivative with low toxicity, 6-deoxybactobolin, showed moderate activity against Gram-positive and Gram-negative bacteria including methicillin-resistant Staphylococcus aureus.
