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.

标 题:Process for the electrosynthesis of ketones
发明人：MOINGEON MARIE-ODILE; CHAUSSARD JACQUES
权利人:POUDRES & EXPLOSIFS STE NALE
摘要:The invention relates to a process for the synthesis of ketones by electrochemical reduction of organic halides in the presence of organic acid anhydrides in an electrolysis cell in an organic solvent medium containing a supporting electrolyte. The anode is a metal chosen from the group consisting of magnesium, aluminium, zinc and their alloys. This process has the advantage of being simple and readily capable of being converted to an industrial scale, particularly because of the possibility of employing a cell which has only one compartment. It can be applied to the electrosynthesis of numerous ketones.

标 题:Synthesis of epothilones and related analogs
发明人：AVERY MITCHELL A
权利人:UNIV MISSISSIPPI
摘要:The present invention relates to methods for use in producing epothilones and analogs and derivatives thereof. A general method according to the present invention broadly comprises performing an aldol condensation of a first compound with a second compound thereby to form a third compound selected from the formulas: n n nand stereoisomers thereof, and performing a macrolactonization of the third compound. The present invention also provides chemical compounds, and methods for producing such chemical compounds, that are useful in producing epothilones and analogs and derivatives thereof.
