标题:一种基于sn(sr)3-物种还原能力的快速还原叠氮化物和硝基化合物的方法
摘要:通过用适量的rsh和et 3 N处理sncl 2或sn(sr)2制备的锡(II)络合物似乎是迄今为止报道的叠氮化物(对胺类)的最佳还原剂.这些锡(II)配合物还可以将伯和仲脂肪族硝基化合物还原为肟,通常在室温下在数分钟之内或数小时之内即可还原成肟,而叔脂肪族以及芳香族硝基化合物也可以还原为相应的羟胺.通常,叠氮化物比硝基取代基反应更快,而羰基,亚砜,砜,腈和酯在相同条件下实际上是不反应的.还阐明了sn(sph)3-与叠氮化物和硝基化合物反应的一些机理细节.

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:A method for preparing a wide range of substituted poly(aniline)s from a single precursor is described. The method uses a variety of reactions, including a boron activation/electrophilic displacement reaction resulting in ipso-substitution. The ability to tune the properties of poly(aniline) through the generation of new structures is useful in numerous fields ranging from polymer-based electronics to sensors.

摘要:Disclosed is a method of the synthesis of ramalin. It comprises reacting a glutamic acid derivative, which is prepared using alkylchloroformate, with a hydrazine salt compound, which is prepared from hydroxy aniline, whether protected or not. The synthesis method allows ramalin, excellent in antioxidant and anti-inflammatory activity, to be simply synthesized at stable yield even without use of a highly toxic solvent such as DMF. In addition, the method is cost competitive, and provides ramalin at high efficiency, thus enabling the mass production of ramalin.
