标题:Chemical amplification for the synthesis of patterned arrays

权利人:AFFYMETRIX INC
摘要:Radiation-activated catalysts (RACs), autocatalytic reactions, and protective groups are employed to achieve a highly sensitive, high resolution, radiation directed combinatorial synthesis of pattern arrays of diverse polymers. When irradiated, RACs produce catalysts that can react with enhancers, such as those involved in autocatalytic reactions. The autocatalytic reactions produce at least one product that removes protecting groups from synthesis intermediates. This invention has a wide variety of applications and is particularly useful for the solid phase combinatorial synthesis of polymers.

摘要:Disclosed is a novel, simple, scalable and environment friendly process for the synthesis of Oroxylin A from Baicalin. Baicalm is esterified to obtain a methyl ester which is further selectively methylated to provide Oroxylin A gluciironide methyl ester which on de- glycosylation results in the formation of Oroxylin A.

摘要:Disclosed is a novel, simple, scalable and environment friendly process for the synthesis of Oroxylin A from Baicalin. Baicalin is esterified to obtain a methyl ester which is further selectively methylated to provide Oroxylin A glucuronide methyl ester which on de-glycosylation results in the formation of Oroxylin A.

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.
