标 题 :Methods and materials for the synthesis of modified peptides
发明人：YOUNG TRAVIS G; KIESSLING LAURA L
权利人:WISCONSIN ALUMNI RES FOUND
摘要:Methods and protected amino acids useful as building blocks (protected monomers) for the synthesis of peptides and proteins that are selectively modified at one or more side-chain hydroxyl groups. Azide-bearing protecting groups allow the selective deprotection of side-chain hydroxyl groups of amino acids after synthesis of a peptide. Reaction conditions for removal of the azide-bearing protecting group can be selected which are substantially orthogonal to those that will remove α-amino protecting groups typically employed in peptide synthesis, such that hydroxyl groups protected with the azide-bearing protecting group remain protected during synthesis of the peptide chain. Various protecting groups which are readily available can be used for protecting potentially reactive side chain groups of amino acids in the peptide or protein to be modified. Preferred side-chain protecting groups are chemically distinguishable from the azide-bearing protecting group and substantially orthogonal reaction conditions can be selected such that side-chain protection of other amino acids is maintained when the azide-bearing protecting group is removed. The use of the azide-bearing protecting group of this invention for one or more hydroxy amino acids during peptide synthesis allows the selective unmasking of those azide-protected side-chain hydroxyl groups and selective modification of the hydroxyl groups that are selectively unmasked. The methods and materials herein are particularly used in synthesis of sulfated, phosphorylated and glycosylated peptides and proteins. Kits and methods of synthesizing a modified peptide or protein using the kits are also provided.

标 题:Synthesis of multi-ring disalicylate linkers
发明人：KAPELEWSKI MATTHEW T; WESTON SIMON C; FALER CATHERINE A
权利人:EXXONMOBIL TECHNOLOGY & ENGINEERING COMPANY
摘要:Systems and methods are provided for synthesizing multi-ring disalicylate linkers. The systems and methods can allow for synthesis of disalicylate linkers while using a reduced or minimized amount of solvent (such as down to potentially having no separate solvent) in the reaction environment. The synthesis can be performed by starting with a compound such as 4,4′-biphenol as a starting reagent. The 4,4′-biphenol (and/or other alcohol-substituted biphenyl compound) can then be exposed in a reaction environment to pressurized CO 2 in the presence of a base. The temperature and pressure in the reaction environment can be increased to achieve either supercritical conditions for the CO 2 (based on a phase diagram for neat CO 2 ) and/or sub-critical conditions that are substantially similar to supercritical conditions. This can allow for conversion of the 4,4′-biphenol (or other alcohol-substituted biphenyl compound) into a multi-ring disalicylate linker.

标 题 :Synthesis of enantiomerically pure amino-substituted fused bicyclic rings
发明人：MCEACHERN ERNEST J; BRIDGER GARY J; SKUPINSKA KRYSTYNA A; SKERLJ RENATO T; YANG WEN
权利人:ANORMED INC
摘要:This invention describes various processes for synthesis and resolution of racemic amino-substituted fused bicyclic ring systems. One process utilizes selective hydrogenation of an amino-substituted fused bicyclic aromatic ring system. An alternative process prepares the racemic amino-substituted fused bicyclic ring system via nitrosation. In addition, the present invention describes the enzymatic resolution of a racemic mixture to produce the (R)- and (S)-forms of amino-substituted fused bicyclic rings as well as a racemization process to recycle the unpreferred enantioner. Further provided by this invention is an asymmetric synthesis of the (R)- or (S)-enantiomer of primary amino-substituted fused bicyclic ring systems.
