标题 :Linkers for synthesis of oligosaccharides on solid supports
发明人：SEEBERGER PETER H; ANDRADE RODRIGO B
权利人:MASSACHUSETTS INST TECHNOLOGY
摘要:The present invention relates to versatile linkers for tethering a molecule to a solid support, e.g., for tethering a monomer, oligomer or polymer to a solid support, which are stable to a wide range of reaction conditions, but can be cleaved under well-defined conditions, thereby liberating the molecule from the solid support. Preferably, the linkers are used to tether to the solid support unprotected, partially-protected or fully-protected monosaccharides or oligosaccharides, or unprotected, partially-protected or fully-protected glycoconjugates. The linkers of the present invention may be used to tether to solid supports building blocks useful in the assembly of libraries of other types of small molecules. The present invention also relates to a molecule or plurality of molecules tethered to the solid support via a linker or linkers of the present invention. The present invention also relates to processes for synthesizing molecules, e.g., monomers, oligomers or polymers, on a solid support, wherein a starting material in the synthesis of the molecule, intermediates in the synthesis of the molecule, and the molecule itself are tethered to the solid support during the process via one of the linkers of the present invention. In certain processes of the present invention, the molecule is liberated from the solid support by cleavage of the linker of the present invention.

标 题:Protecting groups useful in the synthesis of polysaccharides, natural products, and combinatorial libraries
发明人：BUCHWALD STEPHEN L; PLANTE OBADIAH J; SEEBERGER PETER H
权利人:MASSACHUSETTS INST TECHNOLOGY
摘要:One aspect of the present invention relates to optionally substituted halogenated benzyl halides and the like. These compounds are useful as halogenated benzyl ether-based protecting groups for a variety of functional groups. Another aspect of the present invention relates to use of said protecting groups in an orthogonal protecting group strategy for the synthesis of complex molecules that comprise a number of suitable functional groups. Another aspect of the present invention relates to saccharides bearing various arrays of protecting groups of the present invention. Another aspect of the present invention relates to a method of synthesizing an oligosaccharide or glycoconjugate, comprising the steps of: using a saccharide bearing at least one protecting group of the present invention to glycosylate a second molecule to give a product comprising said saccharide; and removing a protecting group of the present invention from said product.

标题:Process for the catalytic synthesis of biaryls and polymers from aryl compounds
发明人：SMITH III MILTON R; MALECZKA ROBERT E
权利人:UNIV MICHIGAN STATE
摘要:A process for producing organic substituted aromatic or heteroaromatic compounds including biaryl and biheteroaryl compounds in a two-step reaction. In the first step, the aromatic or heteroaromatic compound is borylated in a reaction comprising a borane or diborane reagent (any boron reagent where the boron reagent contains a B—H, B—B or B—Si bond) and an iridium or rhodium catalytic complex. In the second step, a metal catalyst catalyzes the formation of the organic substituted aromatic or heteroaromatic compound from the borylated compound and an electrophile such as an aryl or organic halide, triflate (OSO 2 CF 3 ), or nonaflate (OSO 2 C 4 F 9 ). The steps in the process can be performed in a single reaction vessel or in separate reaction vessels. The present invention also provides a process for synthesis of complex polyphenylenes starting from halogenated aromatic compounds.
