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
发明人：FORTUNAK JOSEPH MARIAN; KULKARNI AMOL ANANT; KING CHRISTOPHER
权利人:UNIV HOWARD
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.

权利人:HUNAN MICRO PEPTIDE BIOMEDICAL CO LTD
摘要:Provided is a method for fully liquid-phase synthesis of a GRnH nonapeptide amide analog, which belongs to the technical field of medicine synthesis. The method comprises respectively synthesizing a 'Trp-Ser-Tyr' fragment, an 'R-Leu' fragment, a 'Pyr-His' fragment and 'Arg-Pro-Hunan T', wherein, R = D-Ala (alarelin), D-Leu (leuprorelin), D-Trp (deslorelin) and D-His (histrelin), and obtaining the GRnH nonapeptide amide analog with high yield and high purity by means of a '3 +2 +2 +2' fragment condensation method. The synthesis method is environmentally friendly, mild, and free of any highly toxic and poisonable reagents. The cost is greatly reduced and the synthesis method is very suitable for large-scale production.

标题:Materials and methods for the photodirected synthesis of oligonucleotide arrays
发明人：SERAFINOWSKI PAWEL JERZY; GARLAND PETER BRYAN
权利人:CANCER RES INST ROYAL
摘要:Materials and methods for photodirected synthesis of oligonucleotide arrays on a solid substrate by photodirected synthesis are disclosed which employ a film formed from (i) a photoacid generator that on photolysis generates acid that is capable of directly removing the protecting group of the linker molecules or oligonucleotides and (ii) a polymer substantially lacking electronegative heteroatoms that are capable of hydrogen bonding with photogenerated acid. Methods of synthesizing an oligomer arrays are also described that use a film that restricts diffusion of reactants and products on the substrate during synthesis of the array and which includes a precursor of a deprotecting reagent. The method involves removing one or more of the non-required products of the deprotection reaction from the reactive array elements at which they are produced during the reaction, in order to displace the deprotection reaction towards completion.

权利人:IONIS PHARMACEUTICALS INC
摘要:The present disclosure provides methods of synthesizing modified oligonucletodies and oligomeric compounds (including oligomeric compounds that are antisense agents or portions thereof) comprising a modified oligonucleotide having at least one modified internucleoside linking group. In certain embodiments, the present disclosure provides stabilized formulations of certain sulfonyl azides for use in the synthesis of olignonucleotides comprising one or more sulfonyl phosphoramidate linkages. Some embodiments provide stabilized compositions of high energy reagents that may be used in the synthesis of modified oligonucleotides, allowing for safe process scale preparation thereof.
