标 题 :Catalytic systems for stereoselective synthesis of chiral amines by enantiodivergent radical C—H amination
发明人：Zhang xiao-xiang; Lang kai
权利人:TRUSTEES BOSTON COLLEGE; THE TRUSTEES OF BOSTON COLLEGE
摘要:In one aspect, the disclosure relates to a mode of asymmetric induction in radical processes based on sequential combination of enantiodifferentiative H-atom abstraction and stereoretentive radical substitution. Also disclosed is an asymmetric system for stereoselective synthesis of strained 5-membered cyclic sulfamides via radical 1,5-C—H amination of sulfamoyl azides. The disclosed metalloradical system can control the degree and sense of asymmetric induction in the catalytic radical C—H amination in a systematic manner. The disclosed system is applicable to a broad scope of substrates with different types of C(sp 3 )—H bonds and exhibits reactivity and selectivity, providing access to both enantiomers of useful 5-membered cyclic sulfamides in a highly enantioenriched form. Also disclosed are catalysts useful in these processes. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

标 题:Diversity-oriented synthesis of N,N,O-trisubstituted hydroxylamines from alcohols and amines by N—O bond formation
发明人：CRICH DAVID; HETTIKANKANAMALAGE ASIRI; HILL JARVIS
权利人:UNIV GEORGIA
摘要:In one aspect, the disclosure relates to a method for the direct synthesis of complex N,N,O-trisubstituted hydroxylamines by N—O bond formation. In another aspect, the method can successfully be employed using a wide variety of commercially available alcohols and secondary amines and enables the construction of large fragment-based libraries of trisubstituted hydroxylamines for drug discovery purposes. Also disclosed are N,N,O-trisubstituted hydroxylamines having low basicity, high stability at ambient temperatures, and an inherent lack of reactivity towards acetylating and sulfonylating enzymes that confer mutagenicity on less-substituted hydroxylamines.

摘要:In this method, an oligonucleotide represented by formula (II) [wherein Y 1 , Q, Base, r and r′ are each as defined in claim 1 ] is prepared by using, as a synthesis unit, a novel nucleoside monomer compound represented by formula (I) [wherein X, R 1 , Y, Base, Z, Ar, R 2 , R 3 and n are each as defined in claim 1 ]. The novel nucleoside monomer compound is a nucleoside, the base moiety of which is substituted with an aromatic-hydrocarbon-ring-carbonyl or -thiocarbonyl group having at least one hydrophobic group. The method can dispense with column-chromatographic purification in every reaction, and enables base elongation not only in the 3′-direction but also in the 5′-direction, thus attaining efficient liquid-phase mass synthesis of an oligonucleotide.

标 题:Process for the preparation of polyamines from N-monoaryl-N',N'-dialkyl urea compounds and their use for the synthesis of polyurethanes
发明人：RASSHOFER WERNER; GROEGLER GERHARD
权利人:BAYER AG
摘要:This invention relates to an improved process for the preparation of aromatic polyamines containing urethane and/or biuret and/or urea and/or isocyanurate groups and preferably also ether groups by the hydrolysis of poly-N-monoaryl-N',N'-dialkyl urea compounds (1-aryl-3,3-dialkyl ureas). The ureas are obtained by the reaction of secondary aliphatic, cycloaliphatic or saturated heterocyclic amines with divalent to tetravalent isocyanate compounds containing isocyanate end groups attached to aromatic residues. The ureas correspond to the general formula: wherein R1, R2 denote alkyl or cycloalkyl groups, or together form a ring and A denotes a divalent to tetravalent residue attached to the ureas by aromatic groups. Hydrolysis is carried out in the presence of water and up to two equivalents of a base containing hydroxide ions and/or up to two equivalents of a compound containing tertiary amino groups, optionally in the presence of solvents. The use of the polyamines obtained by this process for the synthesis of polyurethanes is also described.
