摘要:用于羰基化合物还原胺化的低成本和高效催化剂对于可再生生物质的利用至关重要.本文采用模板辅助热解浸渍法制备了一种高效的n掺杂多孔碳负载ni催化剂.在nh 3和h 2存在下,所制备的催化剂可以有效地催化各种羰基化合物还原胺化成相应的伯胺,收率高,稳定性好.综合表征表明,糠醛还原胺化为糠胺与 Ni-N X的形成有关位点和 N 和 Ni 物种在 N 掺杂碳表面上的电子相互作用,促进了co 键的还原胺化,显着降低了三聚体和席夫碱中间体还原氨解的活化能.这项工作为合理设计用于伯胺生产的还原胺化催化剂提供了新的见解.

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 :Green chemistry synthesis of the malaria drug amodiaquine and analogs thereof

摘要:Methods are provided for a green chemistry one-pot synthesis of amodiaquine and amodiaquine analogs. The methods have a lower environmental impact, lower investment cost, reduced amounts of byproducts and impurities, and a shorter synthesis time, compared to current conventional synthesis methods. The methods reduce the total number of steps in the synthesis from four to five down to two, thereby simplifying production; and allow a reduced number of solvents and reagents to be used in production, thereby reducing the waste generated in the synthesis. The methods can reduce the waste to about 3-5 kilograms of waste generated per kilogram of product produced; and surprisingly improve the overall yield from 60-65% to greater than 90% as compared to the current conventional synthesis methods for amodiaquine and its analogs.

摘要:Methods of synthesizing oligonucleotides via new intermediates on a cleavable support having an azidomethyl moiety are disclosed. The method comprises multiple reaction cycles, each of which comprises sequential coupling a nucleoside or oligonucleotide subunit on a cleavable support having an azidomethyl moiety and a nucleoside phosphoramidite or an oligonucleotide phosphoramidite, capping, oxidation/thiolation and deblocking; followed by orthogonal cleavage of the azidomethyl support while keeping all other protecting groups intact. The method can be used in combination with a support moiety for either solid phase or liquid phase oligo synthesis. The soluble support facilitates homogeneous reactions and efficient separations by simple precipitation. The methods also provide novel intermediates useful in the synthesis of oligonucleotide conjugates.
