专利号:WO-9943409-A1 优先权日:1998-02-27 标 题:Hplc fractionation of complex chemical mixtures 发明人:COOK PHILLIP DAN; CUMMINS LENDELL L; GRIFFEY RICHARD H; KAWASAKI ANDREW M; GAUS HANS; AN HAOYUN 权利人:ISIS PHARMACEUTICALS INC; COOK PHILLIP DAN; CUMMINS LENDELL L; GRIFFEY RICHARD H; KAWASAKI ANDREW M; GAUS HANS; AN HAOYUN 摘要:The rapid deconvolution of complex chemical mixtures, such as combinatorial libraries prepared via solution-phase simultaneous addition of functionalities is demonstrated using HPLC. Libraries containing 25-216 members were screened for biological activity and active libraries are fractionated into discreet pools using preferred reversed-phase HPLC. The entire process can be completed from a single synthesis of 15-50 mg, without the need for fixed positions, serial synthesis, or tagging.
专利号:US-6861523-B2 优先权日:2002-02-08 标 题 :1,3,5- trisubstituted-1,3,5-triazine-2,4,6-trione compounds and libraries 发明人:YU YONGPING; OSTRESH JOHN M; HOUGHTEN RICHARD A 权利人:TORREY PINES INST 摘要:The solid-phase synthesis of individual 1,3-disubstituted and 1,3,5-trisubstituted-1,3,5-triazine-2,4,6-triones and libraries thereof from a resin is described. Reaction of resin-bound amino acids with isocyanates yields resin-bound ureas, which further react with chlorocarbonyl isocyanate to selectively afford the resin-bound 1,3-disubstituted-1,3,5-triazine-2,4,6-triones. Selective alkylation at the N-5 position of the resin-bound 1,3-disubstituted-1,3,5-triazine-2,4,6-triones produces a trisubstituted triazinetrione. The products are cleaved from their solid support and obtained in good yield and purity.

专利号:US-7709678-B2 优先权日:2003-10-24 标题:Method for producing asymmetric alkyl compound using alkali-treated solid support, and alkali-treated solid support used in this method 发明人:KOSHIMA HIDEKO; YU HAITAO 权利人:JAPAN SCIENCE & TECH AGENCY 摘要:An asymmetric alkyl compound producing method of the present invention includes a synthesizing step of carrying out an asymmetric synthesis reaction by mixing (i) a reaction solution containing a glycine imine ester, an alkyl halide, and an asymmetric catalyst having a catalytic action which causes the asymmetric synthesis reaction to proceed with (ii) an alkali-treated solid support obtained by treating with an alkaline substance a solid support made of an inorganic compound. By placing this mixture at room temperature, the asymmetric alkylation occurs between the glycine imine ester and the alkyl halide which are catalyzed by the asymmetric catalyst in an alkali-treated solid support contained in the mixture, and the asymmetric alkylation is completed in about 1 hour. Thus, a highly optically pure asymmetric alkyl compound can be obtained in high yield. Therefore, it is possible to provide the asymmetric alkyl compound producing method which does not require the agitation of the solvent, completes the asymmetric alkylation efficiently and stably in a short time, and synthesizes a highly optically pure asymmetric alkyl compound in high yield.
