摘要:在selectfluor的存在下,钯(II)催化剂可将伯酰胺高效且化学选择性地转化为腈.酰胺可以连接到芳环,杂芳环或脂族侧链上,并且该反应可耐受空间体积和电子修饰.含有三个谷氨酰胺基团的肽醇的脱水为每个谷氨酰胺残基提供了构效关系.因此,这种脱水可以通过合成突变与谷氨酰胺的丙氨酸扫描相似.

标题:Synthesis of amine derivatives
发明人：MASUKO FUJIO; KATSURA TADASHI
权利人:SUMITOMO CHEMICAL CO
摘要:An amine of the formula, ##STR1## wherein R 1 , R 2 , R 3 , R 4 and R 5 are each hydrogen, alkyl or the like and n is 1, 2 or 3, including α-phenyl-β-(p-tolyl)-ethylamine, which is useful as an optically resolving agent, an intermediate of medicines and the like, is effectively produced by a novel process comprising hydrolysis of the corresponding nitrile of the formula, ##STR2## wherein R 1 , R 2 , R 3 , R 4 , R 5 and n are the same as above, followed by alkali-decomposition of the resulting amide of the formula, ##STR3## wherein R 1 , R 2 , R 3 , R 4 , R 5 and n are the same as above. An amide including the above one is effectively produced by hydrolysis of the corresponding nitrile in the presence of a base and hydrogen peroxide using an organic quaternary ammonium salt and/or a tertiary amine as a catalyst.
