权利人:HUGHES HOWARD MED INST
摘要:The invention provides novel solid supports for the synthesis of compound libraries. The solid supports have the physical capacity to deliver at least 50 nmol of compound and are functionalized with a silicon-containing linker. In one embodiment of the invention the solid support comprises a bead having a diameter of between approximately 400 and 600 μm functionalized with a silicon-containing linker. According to certain embodiments of the invention the bead is a polystyrene bead. According to certain embodiments of the invention the linker is a diisopropylalkyl-substituted silyl ether. The invention further provides grafted polymeric supports such as lanterns functionalized with a silicon-containing linker. n The invention provides methods for screening in which compounds are synthesized on solid supports in a quantity so that a single solid support such as a bead provides a stock solution sufficient to perform hundreds or thousands of biological or chemical assays. The methods include decoding the sequence of chemical reactions used to synthesize the compound by identifying tags incorporated into the compound during synthesis.

标 题 :Synthesis of unsymmetric anthracene compounds
发明人：CONLEY SCOTT R; COSIMBESCU LELIA; VREELAND WILLIAM B
权利人:EASTMAN KODAK CO
摘要:A process for forming an unsymmetric anthracene compound comprises a first step of forming a 9-perfluoroalkylsulfonate derivative of anthrone by reacting the anthrone with a perfluoroalkyl sulfonating agent, followed by a second step of contacting the reaction product with an aryl or heteroaryl boronic acid, ester or anhydride, and a palladium catalyst for a period of time sufficient to form an unsymmetric anthracene compound having at least one 9-position aromatic substituent.
