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:Method for the synthesis of axially chiral organoboron compounds
发明人：PING YIFAN; CHE CHI-MING
权利人:LABORATORY FOR SYNTHETIC CHEMISTRY AND CHEMICAL BIOLOGY LTD
摘要:A highly efficient and atroposelective Rh-catalyzed [2+2+2] cycloaddition for the synthesis of axially chiral aryboron compounds is developed. The reactions of diynes and alkynylborons smoothly occur in an atom-economical manner, affording a variety of C—B atropisomers in excellent yields and enantioselectivities. The protocol features mild conditions, broad substrate scope, and good functional tolerance. The obtained C—B atropisomers show powerful synthetic applications in terms of producing novel chiral phosphine ligands.
