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.

摘要:Deoxyribonucleotide and ribonucleotide derivatives of the general formula I I wherein R1 represents -CR'R''-Ar, in which Ar is substituted aryl (as hereinafter defined) and R' and R'' are independently selected from the group consisting of hydrogen and lower alkyl; one of -R2 and R3 is a hydroxyl-protecting group and the other is a group suitable for synthesis of polynucleotides or for attachment of the nucleotide to a solid support; R4 is selected from the group consisting of hydrogen, -OH and protected hydroxyl; and B represents a divalent radical corresponding to a purine or pyrimidine base. When synthesis is carried out using these derivatives, the deprotection procedure is reduced to an essentially instantaneous process. The derivatives have acceptable shelf life and are very stable to conventional DNA synthesis conditions. Particularly preferred are those compounds wherein Ar is mono- and dihalo-substituted phenyl.
