The invention also features methods of synthesizing beta-lactones and features novel beta-lactone compounds.
专利号:US-4536599-A 优先权日:1978-08-22 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.
