专利号:US-10829792-B2 优先权日:2017-03-21 标 题 :Biocatalytic synthesis of strained carbocycles 发明人:CHEN KAI; HUANG XIONGYI; KAN S B JENNIFER 权利人:CALIFORNIA INST OF TECHN 摘要:Provided herein are methods for producing products containing strained carbocycles, such as cyclopropene moieties and/or bicyclobutane moieties. The methods include combining an alkyne and a carbene precursor in the presence of a heme protein, e.g., a cytochrome P450, under conditions sufficient to form the strained carbocycle. Reaction mixtures for producing strained carbocycles are also described, as well as whole-cell catalysts comprising heme proteins and variants thereof for forming cyclopropenes, bicyclobutanes, and related products.
专利号:US-7109377-B2 优先权日:1996-10-16 标 题:Synthesis of combinatorial libraries of compounds reminiscent of natural products 发明人:SCHREIBER STUART L; SHAIR MATTHEW D; TAN DEREK S; FOLEY MICHAEL A; STOCKWELL BRENT R 权利人:HARVARD COLLEGE 摘要:The present invention provides complex compounds reminiscent of natural products and libraries thereof, as well as methods for their production. The inventive compounds and libraries of compounds are reminiscent of natural products in that they contain one or more stereocenters, and a high density and diversity of functionality. In general, the inventive libraries are synthesized from diversifiable scaffold structures, which are synthesized from readily available or easily synthesizable template structures. In certain embodiments, the inventive compounds and libraries are generated from diversifiable scaffolds synthesized from a shikimic acid based epoxyol template. In other embodiments, the inventive compounds and libraries are generated from diversifiable scaffolds synthesized from the pyridine-based template isonicotinamide. The present invention also provides a novel ortho-nitrobenzyl photolinker and a method for its synthesis. Furthermore, the present invention provides methods and kits for determining one or more biological activities of members of the inventive libraries. Additionally, the present invention provides pharmaceutical compositions containing one or more library members.

R 1 and R 2 are independently selected from the group consisting of a hydrogen atom, ester group, substituted silyl group, carboxyl group, cyano group, aliphatic C1-C20 hydrocarbon group, and phenyl group. The cis-olefin which is a useful intermediate for the synthesis of fine chemicals is selectively produced in high yields.
