专利号:US-7102023-B2 优先权日:1999-11-24 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.

The present invention further provides the compounds made by the combinatorial synthesis and individually as well as methods of using the same.
专利号:US-9475756-B2 优先权日:2012-03-05 标题:Difluoromethylation of aryl and vinyl iodides 发明人:HARTWIG JOHN; FIER PATRICK 权利人:UNIV CALIFORNIA 摘要:Selectively fluorinated molecules are important as materials, pharmaceuticals, and agrochemicals, but their synthesis by simple, mild, laboratory methods is challenging. We report a straightforward method for the cross-coupling of a difluoromethyl group with readily available reagents to form difluoromethylarenes. The reaction of electron-neutral, electron rich, and sterically hindered aryl and vinyl iodides with the combination of CuI, CsF and TMSCF 2 H leads to the formation of difluoromethylarenes in high yield with good functional group compatibility. This transformation is surprising, in part, because of the prior observation of the instability of CuCF 2 H.
