| titleOfInvention | Method for the synthesis of α β-unsaturated ketones |
| abstract | The present invention relates to a method for the synthesis of alpha , beta -unsaturated ketones which comprises, in the method for the synthesis of alpha , beta -unsaturated ketones represented by general formula <IMAGE> reacting aldehydes represented by general formula R1CHO (where R1 is as defined above) with alkali metal salt of acetoacetic acid represented by general formula <IMAGE>sence as a catalyst of 3-azabicyclo[3,2,2]nonane, a cyclic secondary amine represented by general formula (1) <IMAGE> (1) a cyclic secondary amine represented by general formula (2) <IMAGE> (2) (where, l is 1 or more and up to 6, a ring with N is a 6-membered, 7-membered or 8-membered ring, the two neighbors of N are methylene, R3 is a lower alkyl group, its substitution position is at a carbon atom other than two those adjacent to N, and <IMAGE> is an alicyclic group or a phenol group), or a secondary amine represented by general formula (3) CH3NHCH2R4(3) in a mixuture solvent of water and water-insoluble organic solvent, while keeping the pH constant with mineral acid, and by adjusting an amount of water. |
