任务材料需要提供与化合物相匹配的核心结构和每种化合物合成的详细的参考依据。合格者会得到一定的奖励。将给予每种化合物知识产权转让费9000元,非独家许可使用化合物,以达到研究目的,比如:研究化合物分子的性质和分子衍生物。 Seeking Bicyclic Aminoketones AWARD: varies | DEADLINE: 10/22/12 | ACTIVE SOLVERS: 24 | POSTED: 9/21/12 Source: InnoCentive Challenge ID: 9932910 Type: RTP Detailed Description & Requirements Intellectual Property: In return for the Initial Transfer Fee of $1,500 per compound, you are expected to grant the Seeker only a non-exclusive license to use your compound for internal, research purposes (for example, researching the molecule’s properties or preparing derivatives of the molecule). Material supply of non-commercial compounds matching the shown core structures is desired. For Solvers’ information, procedures for preparing compounds of this type may be found in the following references: Synthesis, 1, 1979, 50. Synthesis, 3, 2010, 493. Tetrahedron, 68 (4), 2012, 1286. J. Organic Chem, 73 (6), 2008, 2114. J. Med. Chem, 37 (18), 1994, 2831. More specifically, the Seeker is looking for compounds that meet the following Requirements: Structure: FeatureRange StructureA bicyclic aminoketone as shown in the structures above. Elements in R and A groupsR = H, Me, or protecting group (preferably Boc) A = A 1-3 membered linker where one atom may be N, O, or S Substituents– In addition to H, the core rings and/or the A linker may be substituted with Me or F. Unsaturation– The core rings and/or the A linker may include an olefin, including an exo olefin, but may not contain any additional carbonyl groups. Additional Rings– The Seeker would prefer compounds that have only the bicyclic structure shown above, however, they may consider compounds with an additional ring fused to the core bicycle. Stereochemistry– The Seeker will only consider compounds which are single diastereomers. In cases where the compound may exist as two enantiomers, the Seeker will consider   [更多]

这项任务要要求设计一个自动化的,高通量的仪器 , 可以定量地和可重复地测定的油水乳化液的分离。 这个任务需要提交一份书面建议书。 An Instrument for Quantitative, Reproducible Characterization of Water/Oil Emulsions AWARD: $30,000 USD | DEADLINE: 10/15/12 | ACTIVE SOLVERS: 508 | POSTED: 8/15/12 Source: InnoCentive Challenge ID: 9933086 Type: Theoretical-IP Transfer Detailed Description & Requirements The presence of emulsions in oil operations is common and generally undesirable. Crude oil emulsions typically form due to the presence of naturally occurring emulsifying agents (asphaltenes, resins, etc.) in crude oil. The high cost associated with transportation and corrosion of equipment is one of the problems caused by the presence of water in the crude oil. Therefore, oil dehydration is required, which is often achieved through chemical treatment using demulsifiers. While the Seeker has identified ~200 liquid “demulsifier” agents, compounds that in amounts of ~100-500 ppm can aid in the resolution of the water and oil phases, they lack a quantitative and reproducible assay for determining demulsifier effectiveness at resolving the emulsion. Currently, the Seeker performs a “bottle test” in which they add ~15-100 mL of the emulsion into a bottle, add the different demulsifiers, shake, and then visually observe which bottles show the best phase separation. This assay clearly relies on visual detection by a trained observer and is not nearly as quantitative or reproducible as the Seeker desires. Results from a bottle test with the same emulsion and three different demulsifiers are shown below. The bottle on the left has clearly not been resolved into two distinct phases. While the middle bottle shows significant improvement, careful inspection of the phase boundary shows a slight amount of oil contaminating the water layer and a slightly undefined interface. Finally, the bottle on the right shows an optimally resolved two-phase system with a very clear oil/water phase boundary. Important Note:   [更多]
