标题 :Process for synthesis of alpha, beta-unsaturated ketones
发明人：PATEL IAN; HOPES PHILIP

摘要:A method for the synthesis of an α,β-unsaturated ketone useful for making substituted 1,4-dihydropyridines is described by reacting an aldehyde with pyrrolidine and then adding a ketone followed by trifluoroacetic acid at low temperature. The synthesis is used in a process for making substituted 1,4-dihydropyridines wherein a vinylogous amide is prepared by reacting a 1,3-cyclohexanedione with a phenylethylamine. The α,β-unsaturated ketone can be reacted with a vinylogous amide to form a 1,5-diketone which can be converted to a substituted 1,4-dihydropyridine.

摘要:A process is described for reacting a vinylogous amide with an α,β-unsaturated ketone in the presence of a silicon compound to form an 1,5-diketone which is converted to a 1,4-dihydropyridine. Asymmetric substituted 1,4-dihydropyridines are synthesized by the process by preparing an asymmetric vinylogous amide by reacting a 1,3-cyclohexanedione with a substantially homo-chiral phenylethylamine. Reaction of the asymmetric vinylogous amide with an α,β-unsaturated ketone in the presence of a silicon compound forms an asymmetric 1,5-diketone. The 1,5-diketone is converted to an asymmetric substituted 1,4-dihydropyridine.
