摘要:合成了分别具有nns,N(Nh)S和nno配体骨架的空气稳定的四角锥形溴化铜(II)配合物1,2和3,并成功用作生物质模型化合物藜芦醇有氧氧化的有效催化剂.水作为一种绿色,可持续的反应介质.综合体2表现出了最好的催化活性.氧化反应在催化量的铜催化剂和 Tempo ((2,2,6,6-四甲基哌啶-1-基)氧基) 存在下,利用空气作为可持续氧化剂,在环境条件 (40 oc) 下成功进行.需要添加外部碱以获得定量产率和对所需醛产物的完全选择性.氧化反应也可以在没有碱存在下进行;然而,随着过度氧化产物藜芦酸的形成,选择性下降.乙腈是氧化反应中最常用的溶剂,甲醇,乙醇,丙酮和乙酸乙酯等各种绿色溶剂也用于同样的目的.尽管乙腈和水具有相似的催化效率,我们在考虑绿色和可持续方面后选择了水.利用优化的水中反应条件将其他木质素生物质衍生的醇以及各种其他取代的苄醇氧化成相应的醛.通过简单的后处理过程(过滤和蒸发

标题:Method for the hydrolysis of substituted formylamines into substituted amines
发明人：BOBYLEV MIKHAIL
权利人:BOBYLEV MIKHAIL
摘要:An improved method for the synthesis of substituted formylamines and substituted amines via an accelerated Leuckart reaction. The Leuckart reaction is accelerated by reacting formamide or N-alkylformamide and formic acid with an aldehyde or a ketone at a preferred molar ratio that accelerates the reaction. The improved method is applicable to various substituted aldehydes and ketones, including substituted benzaldehydes. An accelerated method for the hydrolysis of substituted formylamines into substituted amines using acid or base and a solvent at an elevated temperature. The improved method is useful for the accelerated synthesis of agrochemicals and pharmaceuticals such as vanillylamine, amphetamine and its analogs, and formamide fungicides.

摘要:A process for preparing a N-phenylisoxazolidin-5-one derivative is provided. The process for preparing the N-phenylisoxazolidin-5-one derivative comprises reacting an α,β-unsaturated aldehyde with nitrosobenzene in the presence of a N-heterocyclic carbene (NHC) catalyst. A process for preparing an N-alkoxyphenyl protected β-amino acid ester derivative is further provided. The process for preparing the N-alkoxyphenyl protected β-amino acid ester derivative comprises reacting an α,β-unsaturated aldehyde with nitrosobenzene in the presence of a N-heterocyclic carbene (NHC) catalyst to form a N-phenylisoxazolidin-5-one derivative, and then treating the N-phenylisoxazolidin-5-one derivative with an alcohol in the presence of an acid catalyst. A process for preparing an N-alkoxyphenyl protected β-amino acid ester derivative, comprising treating a N-phenylisoxazolidin-5-one derivative with an alcohol in the presence of an acid catalyst, is also provided.

摘要:Syntheses of steroids such as 3-hydroxy-7α-methyl-21-[2′-methoxy-4′-(diethylaminomethyl)-phenoxy]-19-norpregna-1,3,5(10)triene citrate (“SR 16234â€?) and analogs thereof are provided, wherein 21-hydroxy-19-norpregna-4-en-3-one serves as a starting material or intermediate. The latter compound may be readily prepared from estrone-3-methyl ether. Certain intermediates in these syntheses also have value as therapeutic agents, for example in the treatment of prostate disorders such as prostatic cancer.
