标题:Dynamic covalent chemistry of spiropyrans for synthesis of photoswitchable photoinitiators and uses thereof
发明人：GARMSHAUSEN YVES
权利人:XOLO GMBH
摘要:The present invention relates to spiropyrans and process for the manufacture of them. In particular, a method is provided to exchange the indole and salicylaldehyde part of a spiropyran in a reversible reaction. The method is used for the synthesis of dual color photoinitiators with specific substituents and substitution patterns, which result in improved dual color volumetric printing (xolography). Furthermore, a process for locally polymerizing a starting material by dual color photopolymerization is disclosed.

摘要:The present invention provides biomimetic compounds and libraries thereof, as well as methods for their production. In general, the inventive method involves the selection of a desired biological synthetic pathway and mimics that synthetic pathway utilizing modern synthetic tools. The structures formed from this method are preferably generated in fewer than four steps. These scaffold structures can then be functionalized to yield biomimetic compounds and libraries of compounds. In preferred embodiments, biomimetic compounds and libraries are generated from an oxidative phenolic coupling reaction. In other particularly preferred embodiments, the compounds and libraries of compounds are generated from cascade reactions to yield bicyclo [n. 3.1 ] ring systems, medium ring systems, and fused ring systems. In addition to compounds, libraries and methods for their production, the present invention also provides pharmaceutical compositions and methods and kits for determining one or more biological activities of the library members.
